Microwave properties of (Fe0.82B0.18)0.09La0.05R0.05 amorphous metal alloys
Abstract
Static magnetic field measurements have been reported on amorphous metal alloys of (Fe0.82B0.18)0.90La0.05R0.05, where R=La, Pr, Nd, Sm, Gd, Tb, Dy, Ho, and Er. Microwave properties of these alloys are now reported. The microwave measurements consisted of fixed (9 GHz) and swept (0.01-18 GHz) frequency magnetic resonance experiments. The ferromagnetic resonance (FMR) linewidth, ΔH and g factor were measured. ΔH has a minimum for R=Gd and is equal to 100 Oe. ΔH appears to scale with <LṡS> where L and S are the spin and orbital angular momentum operators of the R ion. The measured g factor obeys the Wangsness relation, as R is varied.
