中文摘要用磁控溅射法制备了GdFeCo/TbFeCo交换耦合两层薄膜,利用不同温度的克尔磁滞回线和VSM磁滞回线研究了读出层(GdFeCo)变温磁化方向变化过程.结果表明,随温度升高读出层从平面磁化转变为垂直磁化,交换耦合两层薄膜具有中心孔探测磁超分辨的基本性能.转变过程主要受饱和磁化强度(Ms)的影响,在GdFeCo的补偿温度附近,读出层的磁化强度较小,退磁场能也较小,在交换耦合的作用下,使读出层(GdFeCo)的磁化方向发生转变.磁化方向的转变在75℃~125℃的温度范围内变化较快.; rs(GdFeCo/TbFeCo) were prepared by sputtering method.The magnetization transition caused by temperature changes has been investigated by the hysteresis loops and the Kerr rotation hysteresis loops.The results indicate that the magnetization direction of readout layer changes from in-plane to perpendicular with temperature increaseing.The films have the basic properties of the CAD-MSR disks.The transition occurs mainly as a result of the changes in the saturation magnetization.When the temperature is increased to the compensation temperature,the saturation magnetization and the demagnetizing energy of the GdFeCo layer decrease,with the exchange-coupled interaction,the magnetization direction of readout layer changes from in-plane to perpendicular.Magneto-optical recording;Magnet
