Abstract
Ferromagnetic resonance linewidths, ΔH, have been measured at 9.5, 24, 38, and 73 GHz for a series of amorphous iron‐boron ribbons with compositions, Fe100−xBx (x=14 to 22). Transmission measurements at 73 GHz have also been carried out to establish the contribution of the bulk intrinsic damping to the frequency dependence of the FMR linewidth. All measurements were carried out over a temperature range of 20–350 °C. The linewidths of the present specimens could be approximately represented by an expression of the form ΔH=ΔH0+(slope)×f; this observation is in agreement with the results reported on the commercial ribbons. The slope was found to be in agreement with the contribution from the intrinsic Landau–Lifshitz damping as measured by transmission. The Landau–Lifshitz damping was found to increase with decreasing boron concentration.This publication has 7 references indexed in Scilit:
