structural and magnetic properties of Fe(20Å) /Ag(xÅ)/Co(20Å) hetro-multilayers

Abstract

- We have deposited Fe/Ag/Co multilayer by physical vapor deposition (PVD)method in different Ag thickness as spacer working in a vacuum of 2×10 -6 mbar. The structural properties , magnetic response of the samples at low temperatures and room temperature was investigated by XRD, physical properties measurement system (PPMS) and vibrating sample magnetometer (VSM) respectively. Hysteresis loops show that the easy axis of magnetization is in plane of the film . Magnetic measurements show dependence of exchange coupling as a pattern of Ag thickness as spacer. magnetic moment shows increasing with decrease of spacer thickness. Also the magnetization and Hc of samples decrease with increasing temperature.
