STRESS DEPENDENCE OF THE MAGNETIZATION PROCESS IN AMORPHOUS WIRES ANDRIBBONS

Magnetization processes in Fe75Si10B15 and (Co92.5Fe6.3Nb1)(77.5)Si7.5 B15 amorphous wires were studied by measuring the stress dependence of the hysteresis loops as well of the pinning field. Disaccommodation m easurements were also used to characterize quenched-in stresses and to study magnetization processes. The results were compared with those o f ribbons with similar compositions. It is shown that the geometry of the samples (wires and ribbons) due to the different cooling condition s determines the different domain structures and consequently the magn etization process.
