Abstract

The magnetic properties of ZrCo5.1-xFex polycrystalline and nanocrystalline alloys are analysed. The saturation magnetizations increase linearly with iron content in both systems, as well as Curie temperatures. The increase in the exchange interactions as result of substitutions induces additional cobalt moments. The anisotropy fields decrease when the iron content increases. This behaviour was correlated with a planar anisotropy of iron sublattice in the present system..
