Abstract
We have studied the uniform mode ferromagnetic resonance in the amorphous systems Metglass 28226A, 2826B, 2826 over the temperature range 77–430 K. The data have been analysed in terms of the Gilbert Equation. The g-values are very similar to those of crystalline permalloy. The relaxation parameters λ, are of the order of 10 8 s −1 and exhibit an interesting temperature dependence. In particular, for T T c ⪅0.5, λ is simply proportional to the static saturation magnetization M s . The present results are compared with those obtained on crystalline samples of the 3- d transition metals and their alloys.
