Abstract

The electrophysical and magnetoresistive properties of permalloy Ni₈₀Fe₂₀ (Py) and Py₆₄Ag₃₆ and Py₆₄Au₃₆ thin films prepared by the electron-beam sputtering are presented. The effect of the addition of a third element (Ag or Au) on the resistivity, temperature coefficient of resistivity and magnetoresistance of permalloy films has been described. The structural, electrophysical and magnetoresistive properties of the investigated samples showed a strong dependence on the annealing temperature.
