摘要：
The thermal, thermomagnetic properties as well as the frequency dependence of permeability are compared for bulk amorphous alloys with the composition of Fe(70.7)C(6.7)P(10.4)B(5)Si(1.1)Mn(0.1)Cr(2)Mo(2)Ga(2) and Fe(65.5)Cr(4)Mo(4)Ga(4)P(12)C(5)B(5.5). The details of devitrification differ mainly in the thermomagnetic measurements. The shape of thermomagnetic curve hints to the formation of hard phase in the case of sample with higher Fe-content. Frequency dependence of the permeability shows unfavorable manner when the temperature of heat treatment approaches the glass transition regime. Contrary, heat treatment at 400 degrees C has a beneficial effect on the high-frequency permeability. (c) 2006 Published by Elsevier B.V.
