STRESS DEPENDENCE OF THE MAGNETIC-PROPERTIES OF AMORPHOUS CO-FE-SI-B ALLOYS

For the amorphous alloys Co//7//5// minus //xFe//xSi//1//5B//1//0 (x equals 0, 2, 4, 4. 6) and Co//7//5Si//5B//2//0, we have studied the stress dependence of the coercive field, the initial susceptibility, the effective anisotropy, and the reduced remanence. The experimental results are in good agreement with a model due to Vazquez, Fernengel and Kronmuller. From our measurements, we obtain the magnetostriction, as well as information about quenched-in stresses and anisotropy mechanisms in these materials.
