Magnetoresistance effect and magnetic properties were examined for Ni-Co-Fe thin films as a function of deposition conditions. The anisotropic magnetoresistivity ratio of above 5% was obtained. ρ_av depends on the substrate temperature and film thickness, but Δρ does not depend. ρ_av and Δρ was measured as a function of temperature. Result show that the temperature dependence of ρ_av is quite similar to that of the MR ratio.
