Abstract

The photothermally modulated ferromagnetic resonance (PM-FMR) has been successfully applied to investigate the position dependence of FMR properties of wedged Fe-samples. The temperature dependence of the surface contribution to the anisotropy could be separated from the demagnetizing field with high accuracy. The oscillating first order interlayer exchange coupling and the anisotropy fields of the Fe-films of a Fe/Cr-wedge/Fe-sample (3.0/0.7–2.8/2.0 nm) were deduced from PM-FMR spectra.
