    Notes:
    Sputtered Co1−xPtx (x=0–0.14) alloy films have been studied by Brillouin scattering of spin waves and compared with results on Co/Pt/Co multilayered films. Brillouin spectra of the surface spin waves in the sputtered alloy films are remarkably broadened as an increase of the Pt content. The in-plane coercivity of the films also increases as the increase of the Pt content, which indicates larger and better oriented grains with proper separations that result from higher Pt content. The broadening of the spin-wave spectra is caused by the magnetic inhomogeneity due to the grains in the film. The exchange stiffness constant of the CoPt alloy films is determined from the magnetic field dependence of the frequency shifts of the surface and standing spin waves. To investigate the exchange interaction in the inhomogeneous alloy films, Co/Pt/Co multilayered films with the Pt interlayer of thickness of 0–40 A(ring) have been fabricated as a model material. From the analysis of the frequency shifts of the spin waves, the exchange interaction between Co layers through the Pt interlayer is evaluated.

    Notes:
    The effects of oxide addition on magnetic and structural properties of sputtered CoNiPt alloy films for high density longitudinal recording with a random c-axis orientation of hcp Co have been studied. It is found that the addition of SiO2 up to 4.2 at. % results in a significant increase in the in-plane coercivity from 1700 to 2400 Oe and a signal to media noise ratio with a slight decrease in coercive squareness from 0.90 to 0.87, while the perpendicular magnetic anisotropy is not significantly changed. X-ray diffraction shows that the c-axis orientation normal to the film plane does not change and the hcp lattice is strained due to the addition of SiO2. A marked decrease in the grain size is observed with the addition of 4.2-at. % SiO2, which causes the development of grain separation and therefore enhances the coercivity. The origin of the increase in coercivity with 2.1-at. % SiO2 is also discussed.

    Notes:
    Sputtered CoNiPt films prepared for high-density magnetic recording media have been studied by Brillouin scattering. The spin-wave spectra in the film are remarkably broadened with width 13 GHz (full width at half maximum), which is much larger than the width of 3 GHz in a film prepared by vapor deposition. Observation by a transmission electron microscope has clarified that the sputtered film consists of Co crystallites with a diameter of 50–100 A(ring), which are separated from each other. The remarkable damping of the spin waves in the sputtered CoNiPt film is caused by the film structure. The film is, however, elastically homogeneous, which is known from the undamped surface acoustic wave spectra. The result shows the segregation of the nonmagnetic Pt-related alloys takes place between the Co crystallites. The exchange stiffness constant was determined as 2.4×10−9 Oe cm2 in the sputtered film, which is 1/1.7 that in the vapor-deposited films.
