Abstract
We present a technique of measuring hysteresis loops of the amorphous microwires using a method of vibrating-sample magnetometry. Control magnetic measurements were carried out on samples of an amorphous microwire of Fe 75 B 13 Si 10 C2 composition in a glass shell obtained by the Ulitovsky – Taylor method. The sample was fixed on a specially manufactured experimental setup which enables us to stretch the microwire by means of suspended loads. Fixation of the microwire in the stretched state was carried out by the glue. The stresses in the metal core of the microwire formed upon stretching with suspended loads, as well as the stresses in the contact area of the wire and glue are calculated. The developed method provides fixing of tensile stresses in wires even when the value of stresses may attains a few GPa.
