    Notes: This study provides a method for improving the corrosion resistance of rare-earth–transition-metal films used for magneto-optical recording without depressing the recording sensitivity. This was attained by increasing Co content and substituting Dy for Tb and TbFeCo amorphous films. Potentiostatic polarization measurements indicate that the pitting potential of the film increases with the increase of Co content up to y=0.17 for (Tb0.5Dy0.5)0.21Fe0.79−yCoy. Attempts are made to explain the results using Auger electron spectroscopy and x-ray photoelectron spectroscopy. For the above-noted composition, both the Kerr rotation angle and coercivity observed through the substrate retain their initial values after the accelerated aging test. Results indicate that the (Tb0.5Dy0.5)0.21Fe0.62Co0.17 film offers superior characteristics for corrosion resistance without disturbing the magnetic properties.

    Compositional dependence of recording noise in amorphous rare-earth–transition-metal magneto-optical disks (1988)

    Notes: The compositional dependence of recording-power sensitivity and recording-noise characteristics of TbFeCo and TbDyFeCo films have been studied systematically. The sensitivity depends on the compositional ratio of rare earth (RE) and transition metal (TM) rather than on Co content. This is explained by the fact that the temperature at which the coercive force (Hc ) coincides with the bias magnetic field of 500 Oe, hereafter denoted as T', varies drastically by altering the RE-to-TM ratio. High recording noise is observed for compositions having Tcomp close to TC. When TC−Tcomp(approximately-greater-than)70 °C, optimal carrier-to-noise ratios are obtained. These results are explained qualitatively by the behavior of domain-wall motion in the vicinity of the magnetically reversed domain.
