【摘要】 本文讨论了稀土-过渡金属（以下简写为 RE-TM）非晶合金膜用作磁光记录介质的理论和 TbFeCo 膜的特性。采用射频溅射技术制备出 TbFeCo 非晶垂直磁化膜。膜的垂直各向异性常数K_u 为2.94×10^5J/m³,克尔旋转角θ_k 为0.24-0.29°。得到了θ_k 随过渡金属 Co 含量而变化的曲线。当 Co 在 TM 次网络中含量达50%时,θ_k 有最大值0.29°。在膜被复盖一层 SiO₂或 AlN 之后,θ_k 从0.29°提高到0.55°或1.48°。（TbFeCo+AlN）膜的θ_k 达到1.48°这样高的值,尚未见文献报导。这种膜可以直接用作磁光记录介质。更多还原

【Abstract】 In this paper the theory of the amorphous rare earth-transitionmetal（RE-TM）alloy film which is used as magneto-optical recording mediaand the properties of TbFeCo film were discussed.The amorphous TbFeCo filmwith perpendicular magnetization has been prepared by RF sputtering technique.The perpendicular anisotropy constant K_u and Kerr rotation angle θ_k of thefilm are 2.94×10⁵J/m³ and 0.24—0.29°,respectively.The curve of θ_k cha-nge with the content of transition metal Co was obtained.When the contentof Co in the TM subnetwork reaches 50%,the θ_k has a maximum value of0.29°.After the film is coated with a SiO₂ or a AlN thin layer,θ_k is en-hanced from 0.29°to 0.55°or 1.48°.It has not reported so far that the θ_kvalues of TbFeCo/AlN film was up to 1.48°the film can be directly used asmagneto-optical media.更多还原
