Microwave Resonance Study of Crystallization of Amorphous Metallic Alloys
RÉSUMÉ
The microwave resonance method (ferromagnetic resonance method) is applied to study the effect of annealing on the magnetic properties of amorphous metallic iron-based materials (Fe-B-Si-C) with the Fe-content near 70 %. The magnetization and the spectroscopic splitting factor (g-factor) are studied in the samples annealed in the wide temperature range (the annealing temperatures varied from 200 °C to 400 °C, the annealing time was 50 min). It is concluded that the observed saturation of the magnetization and the g-factor are caused by the crystallization processes taking place at the annealing temperatures above 300 °C. This conclusion agrees with the fact that the annealing temperatures corresponding to crystallization of similar amorphous iron-based alloys get into the same temperature interval according to the literature.
