摘要：

NiFe alloy films with thicknesses in the range from 60 to 150 angstrom were sputtered onto Si ( 0 0 1) wafers by DC magnetron sputtering, and then characterized by in-plane ferromagnetic resonance technique ( FMR) at x-band. The FMR field ( H-R) and linewidth ( DH) were studied as a function of the in-plane angle, phi(H) film thickness, t, and temperature, T. The main effects of temperature on the magnetic properties of these. lms is to increase the in-plane uniaxial anisotropy and to induce a surface anisotropy that pushes the magnetization out-of-plane. These anisotropies were found to vary with thickness and temperature. The main processes that determine the line broadening are the intrinsic conduction mechanism and the in-plane uniaxial dispersions. (c) 2007 Elsevier B. V. All rights reserved.
