- 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.
