摘　　要：用化学沉淀法制备了纳米薄膜Ni100-XPX（X=2．40，2．89，3．21，3．60，4．64，5．45，7．64）系列样品。用Scherrer法计算出组成薄膜的颗粒的尺寸为7～15nm。利用振动样品磁强计测量了材料的磁学参数。对晶格常数、饱和磁化强度、居里温度与磷含量的关系进行了详细的分析。The series of Ni100-XPX nanofilm has been studied by the means of X-ray defraction analysis, oscillating sample magnetometer. The dimension of nanoparticles is about 7- 15 nm. the hysteresis loops with superparamagnetic characters has been observed for all samples. The component dependence of crystal lattice constant, saturated magnetization and Curie temperature has been analyzed.
