用真空蒸发工艺制备了ＮｉｘＡｇ１－ｘ颗粒膜，在不同温度下研究了磁性和磁电阻与热处理温度和成分的关系。发现，在Ａｇ基质中，制备态膜的Ｎｉ颗粒很小，电镜分析看不出Ｎｉ的ｆｃｃ结构，经２００℃×１０ｍｉｎ退火可以看到Ｎｉｆｃｃ衍射环。在１．５Ｋ磁电阻可达９％，饱和磁化强度约５２±３ｅｍｕ／ｇ．
NixAg1-x granular films were prepared by vacuum evaporation process. The relationship between magnetic and magnetoresistance and heat treatment temperature and composition was studied at different temperatures. It was found that the Ni particles in the Ag matrix were small and the fcc structure of Ni was not observed by electron microscopy. The Nifcc diffracting ring was observed after annealing at 200 ℃ for 10 min. In 1.5K magnetic resistance up to 9% saturation magnetization of about 52 ± 3emu / g.
