| Abstract |
Thermal effects on the initial permeability and the disaccommodation have been studied in amorphous (Co_(0.94-x),Fe_(0.06)M_x,)_(78)Si₄B_(18), alloys (M=Cr and Ta, x=0-0.08). Initial permeability decreases with increasing temperature, and this tendency reduces after heat treatment. Alloys containing Cr and Ta of x=0.04 with near zero magnetostriction show low decreasing rate of permeabilities at elevated temperature. The low temperature disaccommodation is smaller in alloys containing Ta which has larger atomic radius and strong chemical affinity with Fe than in Cr added alloys. The lowest disaccommodation at elevated temperature has been obtained in amorphous alloy containing Ta of x=0.04. |
