摘要：
A systematic variation of film composition was done during electrodeposition of NiFe thin films onto 100 mu m diameter copper wire. Current density of deposition was maintained at 20 mA/cm(2) to ensure constant film thickness. Pure Ni film as well as Fe rich NiFe film were not magnetically soft enough and showed poor magnetoimpedance effect. As Fe concentration was systematically varied, softest magnetic properties and magnetoimpedance value were found for the film composition Ni79Fe21. Soft magnetic properties induced and magnetoimpedance effect observed at this composition was attributed to the lowering of magnetoelastic anisotropy as well as magnetocrystalline anisotropy.
