摘要: 用射频磁控溅射法制备了金属/半导体Fex(In2O3)1-x颗粒膜,研究了该系列颗粒膜的微结构和磁性.实验结果表明:纳米尺度的Fe颗粒均匀地分散在非晶态In2O3中.室温下样品具有超顺磁性,符合朗之万方程.

关键词: 微结构, 颗粒尺寸, 超顺磁性

Abstract: Metal/semiconductor Fex (In2O3)1-x granular films are prepared by RF sputtering method. The microstructure and magnetic properties are studied. The experiment results showed that the nanometer-sized Fe particles uniformly dispersed in the amorphous In2O3. At room temperature, the film shows superparamagnetic behavior, following the Langevin equation.

Key words: microstructure, grain size, superparamagnetism
