FMR and FMAR fields measured on Fe—3.16 wt% Si single crystals between 3.5 and 300 K at microwave frequencies between 35 and 96 GHz are used to evaluate the saturation magnetization μ 0 M s , the first magnetocrystalline anisotropy constant K 1 , and the g ‐factor temperature dependences with accuracies of ±0.5 mT, ±0.15 kJ/m 3 , and ±0.0004, respectively. The g ‐factor is found to be temperature independent and the temperature dependence of μ 0 M s is described according to the spin‐wave theory.
