摘要：

The dependence of the magnetic structure and the hysteresis properties of the amorphous microwires on the applied load is investigated by the magnetic-optical method of the indicator films and the inductive pickup coils. We examine the amorphous microwires of Fe73.5Cu1Nb3Si13.5B9 and Fe7.75Si7.5B15, with a positive magnetostriction and different thickness of the glass coating and the diameter of the metal core. An increase in the stress level can be achieved by stretching along a microwire axis. The hysteresis properties and magnetic domain structure are examined during in situ stretching. Coercivity versus tension curves have been plotted for the examined microwires. It is shown that an increase in the stress leads to an increase in the coercivity.
