FMR Studies of Ultra-Thin Epitaxial Pd<inf>0.92</inf>Fe<inf>0.08</inf>Film

Abstract

© 2017, Springer-Verlag GmbH Austria. Magnetic anisotropies of 20 nm epitaxial film of palladium–iron alloy Pd0.92Fe0.08grown on the (001) MgO substrate were studied. Ferromagnetic resonance (FMR) spectroscopy and vibrating sample magnetometry (VSM) were exploited to determine magnetic parameters of the film. It was found that the synthesized film reveals cubic anisotropy with tetragonal distortion. The simulated magnetic hysteresis loops, obtained utilizing the magnetic anisotropy constants taken from the FMR spectra analysis, agree well with those measured by VSM.
