Popis:	Thermomagnetic analysis of the initial AC susceptibility of amorphous CoFeSiB wire shows strong stabilization of the domain structure. The initial susceptibility of the as-cast sample drastically decreases in the temperature range (100-250)°C due to directional reordering. A special form of the hysteresis loop is a consequence of large internal stresses introduced in the wire by the rapid melt quenching. It was shown that in the as-cast state the stabilization leads to the reduction of the number of Barkhausen jumps into one large Barkhausen jump at temperatures above 100°C. After stabilization at 150°C, the sample shows almost bistable behaviour even at room temperature.
