【Abstract】 The microstructural feature of SmCo magnetic thin film prepared by co-evaporation with two heating sources and its dependence on composition and temperature were investigated with TEM and SEM. The formation of the amorphous SmCo magnetic thin films as well as the influence of the micro-structure on the magneto-optical properties is discussed. Experimental results show that SmxCo100-x (15<x≤40) magnetic thin films possess amorphous microstructure consisting of small rod-shaped regions (about 3 nm in diameter) with high density and a network of less-dense material (1.5-2.0 nm in thickness). The crystallization temperature of amorphous SmCo magnetic thin films is abous 573°K.更多还原
