Abstract

In this work, we present a study of the magneto transport properties in magnetic multilayered structure \(\text{ Ni }_{81}\text{ Fe }_{19}\text{/Zr }\). The magnetic \((\text{ Ni }_{81}\text{ Fe }_{19})\) and non magnetic (Zr) layer thickness \((\mathbf{t}_\mathbf{NiFe}, \mathbf{t}_\mathbf{zr})\) effects on the magneto resistance (MR) are discussed theoretically in the framework of the Johnson–Camley semi classical approach based on the Boltzmann transport equation. A comparison between calculated and measured MR is obtained. The observed MR ratio oscillates for Zr layer thickness with an average period of 7Å. A generally weak \(\text{ MR }(\text{ t }_{\mathrm{NiFe}})\) ratio for fixed \(\mathbf{t}_\mathbf{zr}\) is obtained and it shows a maxima peak of the MR with a value of 1.8 % located at \(\mathbf{t}_\mathbf{NiFe}= 80\)Å.
