Published 1991Staff ViewISSN: 1089-7550Source: AIP Digital ArchiveTopics: PhysicsNotes: Amorphous LRE-TM SmCo perpendicular magnetic film provides a promising candidate for perpendicular magnetic recording media.1 In order to improve the magneto-optical properties of SmCo films, we have studied the ternary system: Smy(Co100−xDyx)100−y films which were prepared by rf magnetron sputtering system. Because the Dy moment is antiferromagnetically coupled to the Co moment and Dy has a larger magnetic anisotropy, Dy addition will increase Ku and decrease Ms of LRE-TM films. With the Dy addition content increased from 0 to 10 at. %, the perpendicular anisotropy constant K⊥ (K⊥ = Ku(K⊥=Ku− 2πM2s) increased to improve the magneto-optical properties of SmCo films. The torque curve measurement and Kerr hysteresis loop of SmCoDy film had proved it was perpendicular magnetic film. In order to prevent RE metal selective oxidation of SmCoDy films, a protective layer AlN was used. AlN films were prepared by rf reactive sputtering.2 The temperature dependence of AlN/SmCoDy/glass were studied. Hc decreased rapidly when temperature increased while its Kerr angle decreased slightly. When the sample was cooled to room temperature, Hc and θk returned to its original value. The results show SmCoDy films may become new material of magneto-optical recording media. The long-term stability and microstructure of SmCoDy films have also been studied.Type of Medium: Electronic ResourceURL: -

Published 2002Staff ViewISSN: 1089-7550Source: AIP Digital ArchiveTopics: PhysicsNotes: In order to increase the crystallization speed and data transfer rate (DTR), a superlattice-like structure (SLL) was applied to the recording layer of phase change optical disks. Unlike the conventional phase change layer, the recording layer with the SLL structure consisted of alternating thin layers of two different phase change materials, i.e., GeTe and Sb2Te3. Although neither GeTe nor Sb2Te3 could be used as a phase change layer material for practical applications, present experimental results revealed that the phase change optical disk with the SLL structure demonstrated an excellent recording property that could meet practical recording requirements. X-ray photoelectron spectroscopy was employed to confirm that the SLL structure could be preserved after many times of melting and quenching. Dynamic properties of the optical recording disk with the SLL structure were investigated with a 1 T pulse duration of 8 ns and a constant linear velocity of 19 m/s. A clear eye pattern was observed. The carrier-to-noise ratio was about 58 dB and a DTR of 47 Mbit/s was achieved. The DTR would be as high as 140 Mbit/s if the blue light is used. It has been proven that the SLL structure is a useful means to increase the DTR of phase change optical recording disks. © 2002 American Institute of Physics.Type of Medium: Electronic ResourceURL: -

Published 1997Staff ViewISSN: 1077-3118Source: AIP Digital ArchiveTopics: PhysicsNotes: Synchrotron radiation photoelectron spectroscopy combined with scanning electron microscopy (SEM) and gravimetry has been used to study GaAs (100) surfaces treated with a neutralized (NH4)2S solution. Compared to the conventional basic (NH4)2S solution treatment, a thick Ga sulfide layer and strong Ga–S bond were formed on the GaAs surface after dipping GaAs wafers in a neutralized (NH4)2S solution. Gravimetric data show that the etching rate of GaAs in the neutralized (NH4)2S solution is about 15% slower than that in the conventional (NH4)2S solution. From SEM observation, fewer etching pits with smaller sizes were found on the neutralized (NH4)2S-treated GaAs surface. © 1997 American Institute of Physics.Type of Medium: Electronic ResourceURL: -

Published 1997Staff ViewISSN: 1077-3118Source: AIP Digital ArchiveTopics: PhysicsNotes: AlN film with high transmissivity was deposited onto organic photoconductor (OPC) surface and the surface hardness was increased by between 31.9% and 61.5%, and the surface roughness was also decreased. The electrophotographic properties of the OPC coated with AlN film were also improved, thus confirming the suitability of AlN film for enhancing the operating life of OPC. © 1997 American Institute of Physics.Type of Medium: Electronic ResourceURL: -

Published 1990Staff ViewISSN: 1089-7550Source: AIP Digital ArchiveTopics: PhysicsNotes: RE-TM amorphous thin films with perpendicular magnetic anisotropy are promising for use in erasable optical recording media. In order to improve the drawback of easy oxidation and lower C/N of RE-TM films, some protective layers such as SiO, SiO2, ZnS, AlN, and Si3N4 films were studied.1,2 We have studied the Kerr effect enhancement and corrosion resistance improvement by AlN and AlSiN films. AlN and AlSiN films were prepared on glass, PC, and PMMA substrates by a rf magnetron sputtering system with three targets using low sputtering power. The films have a high refractive index (2–2.15), high optical transparency (over 90%), and high stability. The relation between optical properties and rf reactive sputtering conditions (Ar: N2 ratio, total pressure, sputtering power, sputtering time), composition, spectral transmittance, and uniformity of sputtering AlN and AlSiN films were studied. The Kerr rotation angle was up to 1.5° in AlN/TbFeCo/glass and AlSiN/TbFeCo/glass multilayer structures (laser is incident from air). We also studied AlN/TbFeCo/AlN/glass, AlN/TbFeCo/AlN/Al/glass, AlSiN/TbFeCo/AlSiN/glass and multilayer structure films. The results show that AlN and AlSiN films provide sufficient Kerr effect enhancement and superior corrosion resistance improvement to the RE-TM films. The microstructure of those films were also studied by JEM, XRD, and XPS.Type of Medium: Electronic ResourceURL: -

ISSN: 1432-0703Source: Springer Online Journal Archives 1860-2000Topics: Energy, Environment Protection, Nuclear Power EngineeringMedicineNotes: Abstract. Polychlorinated biphenyls (PCBs) and metals were analyzed in coral (Porites lobata), fish (Stegastes fasciolatus), crab (Grapsus tenuicrustatus), and sediment samples collected from Tern Island, and the reference samples from Trig and La Perouse Islands. All three islands are part of French Frigate Shoals, a national wildlife refuge in the North Pacific Ocean. Average concentrations of total PCBs ranged from 154 to 274 ng/g in the sediments, from 120 to 267 ng/g in the corals, from 387 to 4,500 ng/g in the crabs, and 1,340 to 46,000 ng/g, dry weight, in the fishes. High concentrations in marine species indicate there is PCB source(s) in French Frigate Shoals, especially Tern Island. Tetra- and pentachlorobiphenyls were 64–66% of the total PCB levels in the sediments, and they accounted for 57–65% of total PCBs in the corals. Penta- and hexachlorobiphenyls were 76–84% of total PCBs in the fishes, and they accounted for 79–85% in the crab samples. The sediment and coral were predominated by lower chlorinated PCB congeners, whereas the fish and crab bioaccumulated mainly higher chlorinated congeners. Selenium concentrations (16–23 μg/g) in sediments were much higher than some reported baseline values (0.4–2.5 μg/g). The average concentrations of arsenic, cadmium, lead, and selenium in the coral and fish were about equal to or less than those in the sediments. Concentrations of arsenic and cadmium in the crabs (49–51 and 3–4 μg/g, respectively) were approximately twofold of those in the sediments.Type of Medium: Electronic ResourceURL: -

ISSN: 1573-4803Source: Springer Online Journal Archives 1860-2000Topics: Mechanical Engineering, Materials Science, Production Engineering, Mining and Metallurgy, Traffic Engineering, Precision MechanicsNotes: Abstract Zirconia-alumina multilayer nanolaminate coatings were applied on stainless steel 316 substrates by a sol-gel dipping method. The coatings were characterised using X-ray diffraction, optical and scanning electron microscopy. The hardness and elastic modulus, the wear resistance and the oxidation resistance of the coatings were measured and assessed. It was observed that the coatings possessed fine grains, fine pores and high retention of tetragonal zirconia phase. The coatings exhibited high hardness and elastic modulus as well as good resistance to oxidation at high temperatures. However, these properties may be influenced by the interactions at the coating/substrate interface.Type of Medium: Electronic ResourceURL: -
