Fe 45 Ag 55 颗粒膜的磁光尺寸效应

Using X-ray diffraction, vibrating sample magnetometer and magneto-optical measurement, the structure, magnetism and magneto-optical properties of the Fe 45 Ag 55 granular films for different annealing temperatures have been studied. The sampels were prepared by ion beam sputtering. Results show that magneto-optical Kerr effect are closely related to particle size.
