| 摘 要： | 制备了三元GdFeCo合金薄膜和四元NdGdFeCo合金薄膜,测量了其磁饱和磁化强度对温度的依赖关系、磁滞回线以及可见光范围内的克尔谱.研究了轻稀土Nd掺杂对GdFeCo磁光薄膜的克尔旋转角的影响,发现在一定掺杂范围内能够有效提高薄膜在短波长下的克尔旋转角.掺入适量的轻稀土Nd可以使GdFeCo薄膜在短波长下的磁光性能提高,更好的适用于作为中心孔探测磁超分辨的短波长磁光读出层材料.

| Abstract: | The GdFeCo and NdGdFeCo thin films were prepared by sputtering, and their hysteresis loops, temperature dependence of the saturation magnetization M_s and magneto-optical Kerr spectrum in the visible light range were measured. By studying the effects of light rare earth element Nd doping on the magneto-optical Kerr rotation angle of GdFeCo thin films, it is found that proper Nd additives in GdFeCo films could enhance Kerr rotation at short wavelengths. So it could be better medium used as the readout layer of center aperture detection magnetically induced super resolution (CAD-MSR). |
