Abstract

The angular variation of the FMR linewidth in single crystal disks of nickel has been studied for both the in‐plane (H) ∥ sample surface) and out‐of‐plane (H ⊥ sample surface) geometries. For the in‐plane case the linewidth is essentially isotropic. For the out‐of‐plane geometry the effective linewidths exhibit a shallow minimum for M about 55° from the sample plane. For both geometries these results are consistent with a Gilbert type equation (including exchange conductivity effects) with an angle independent damping parameter.
