Published 2000Staff ViewISSN: 1089-7550Source: AIP Digital ArchiveTopics: PhysicsNotes: The adhesion of an ultrathin carbon nitride (CN) coating to the surface of a two-phase CoPt–SiO2 granular film heterogeneous at the 10 nm scale has been studied using nanoscratch techniques. The nanoscratch resistance was found to depend sensitively on the volume fraction of the two phases. Both nanoscratch experiments and complementary electron microscopy observations indicate that CN adheres much more strongly to the SiO2 matrix than to the CoPt granules resulting in enhanced tribological performance in SiO2-rich films. The relative weakness of the CN/CoPt interface is correlated to the absence of interfacial metal nitride formation. The adhesion of the CN coating to the granular surface, the intrinsic mechanical properties of the underlying granular film (nanoindentation hardness and modulus), and the vertical rms surface roughness of the granular layer are all fundamentally changed as the CoPt content reaches the percolation threshold. © 2000 American Institute of Physics.Type of Medium: Electronic ResourceURL: -

Published 1998Staff ViewISSN: 1089-7550Source: AIP Digital ArchiveTopics: PhysicsNotes: The magnetic properties and microstructure of as-deposited and annealed Fe–SiO2 granular thin films were studied. As-deposited films have a maximum in coercivity at an Fe volume fraction (Fe vol %) ∼62% independent of film thickness. Iron grains in as-deposited films are well defined, nearly equiaxial and ∼5 nm in diameter. From 66 to 90 Fe vol %, some as-deposited films showed an unusual well defined in-plane uniaxial anisotropy. The magnetic percolation threshold, xp, as indicated by the maximum in the Hc vs Fe vol % curve, changed after the films were annealed. The percolation threshold (xp) of films annealed at 420 °C for 30 min shifted to ∼47 Fe vol % except for the 5 nm films, whose xp remained unchanged. After annealing at 510 °C for 3 h, a strong thickness dependence of the percolation threshold was revealed in films thinner than 40 nm, with values ranging from 78 Fe vol % to less than 44 Fe vol %. The shifts of xp in both 420 and 510 °C annealed films can be explained by the effects of reduced dimensions in very thin films. © 1998 American Institute of Physics.Type of Medium: Electronic ResourceURL: -

Published 2000Staff ViewISSN: 1089-7550Source: AIP Digital ArchiveTopics: PhysicsNotes: The magnetic and structural properties of a series of granular Co/CN films prepared by annealing multilayers of Co and CN have been studied. The films contained both hcp and fcc phases, and grain sizes were in the range 18–27 nm. The coercivity varied with cobalt fraction and with bilayer thickness, and a maximum room temperature coercivity of 1230 Oe was obtained for 50% cobalt and 2.7 nm bilayer thickness. Measurements of the time and temperature dependence of the highest coercivity films suggest that their coercivity is due primarily to the hcp phase and to the grain size. All films had relatively low values of magnetic viscosity (2%–3%/decade). © 2000 American Institute of Physics.Type of Medium: Electronic ResourceURL: -

Published 2001Staff ViewISSN: 1077-3118Source: AIP Digital ArchiveTopics: PhysicsNotes: Using a combination of high-resolution x-ray reflectivity (XRR), nanotribological, and x-ray photoelectron spectroscopy (XPS) techniques, a thorough description of the structural parameters of ultrathin CNx overcoats on CoCr magnetic films is obtained. In addition, the tribological performance as a function of deposition energy is shown to correlate well with trends found by XRR and XPS. © 2001 American Institute of Physics.Type of Medium: Electronic ResourceURL: -

Published 1999Staff ViewISSN: 1089-7550Source: AIP Digital ArchiveTopics: PhysicsNotes: Time decay and remanence measurements have been made on a series of very thin Fe–SiO2 granular thin films of varying composition. The susceptibility and the magnetic viscosity decreases drastically when the film thickness is thin enough to reach a two-dimensional arrangement of the granules. The measured values of the magnetic viscosity are very low (2% loss per decade) in the thinnest films so that further investigations in granular magnetic systems with higher anisotropy promise greater advantages for recording media. © 1999 American Institute of Physics.Type of Medium: Electronic ResourceURL: -

Published 1999Staff ViewISSN: 1089-7550Source: AIP Digital ArchiveTopics: PhysicsNotes: In the Fe–SiO2 granular system the effects of oxidation and abnormal grain growth on the magnetic behavior are significant. As film thickness is reduced a larger fraction of Fe grains intersect the free surface and are prone to oxidation even in good vacuum conditions. Films coated with protective SiO2 layers were found to be unaffected by oxidation. The presence of a surface during annealing also affects the microstructural evolution. Transmission electron microscopy observations revealed a bimodal distribution of Fe grain sizes in uncoated films due to grain merger assisted by surface diffusion. This bimodal distribution of Fe grain sizes is associated with a coercivity (Hc) vs vol. % Fe curve containing two peaks. By contrast, SiO2 coated films exhibited a uniform microstructure without unusually large grains and a smoother Hc vs vol. % Fe curve with a well defined maximum. Room temperature coercivities of ∼1000 Oe can be routinely achieved in Fe–SiO2 granular films as thin as 10 nm. X-ray photoelectron spectroscopy studies showed evidence for the chemical interaction between Fe and SiO2 in SiO2/Fe/SiO2 trilayer model film samples. © 1999 American Institute of Physics.Type of Medium: Electronic ResourceURL: -
