摘要：
In this work, we present a study of the structural, magnetic and magnetotransport properties in magnetic multilayered structures (NiFeCo/Cu) at room temperature. The magnetic (m) and nonmagnetic (nm) layer thickness (t(m), t(nm)) and the composition of the magnetic layer effect on the magnetoresistance (MR) have been investigated experimentally and discussed theoretically in the framework of the Johnson-Camley semiclassical approach, based on the Boltzmann transport equation. The observed MR ratio oscillates for the Cu layer thickness with an average period of 12 Angstrom and decreases from one system to another less rich in Co. The MR peak position depends on the magnetic layer composition, The materials become harder with increasing Co concentration.
