| Annotation | The results of the experimental studies of the structural and phase state, magnetic and magnetoresistive properties of thin films of Ni-Fe-Co alloy with the initial concentration of components сNi 40, сFe 10, and сCo 50 at.% in the annealing temperature range of Тa 300-1000 K are presented. It is shown that as-deposited alloy films have a two-phase structure fcc-Ni3Fe + hcp-Co. The fcc-phase with the lattice parameter of 0,354 nm, which corresponds to Ni-Fe-Co solid solution, is observed after heat treatment at 900 K. Thin films based on Ni-Fe and Co exhibit anisotropic magnetoresistance with the highest value (0,35%) observed in the perpendicular measurement geometry. The value of magnetoresistance tends to rise with increasing annealing temperature. The results of the magnetic and magnetoresistive measurements indicate the presence of the easy axis of magnetization in plane of the sample. |
