摘要：

The correlation between microstructure and quasi-static magnetic hysteresis loop of the initially amorphous ribbons of Fe76.5-xCu1NbxSi13.5B9 alloys after annealing for 1 h at 370-800 degrees C was studied, The local minimum of coercive field H-cmin was observed for the alloys after completion of the first stage of crystallization. The observed decrease of H-cmin from 83 to 0.5 A/m is ascribed to the decrease of an average diameter D of alpha-Fe(Si) nanocrystals from 62 to 12 nm, while niobium content x increases from 0 to 3 at%, respectively.
