Abstract
The influence of temperature on the dependences of the ΔE effect of Fe75Si10B15 metallic amorphous wires, which were subjected to thermomagnetic treatment at temperatures of from 370 to 470°C, on the magnetic field has been studied. It was shown that, at all temperatures of thermomagnetic treatment at relatively low heating temperatures, the negative ΔE effect is observed. The increase in the heating temperature of the wire during measurements of the ΔE effect at temperatures of 30–330°C leads to a decrease in both the magnitude of negative ΔE effect and the field of reaching the maximum ΔE effect magnitude. The dependence of the induced anisotropy field on the heating temperature of the wire has been determined. The obtained results are explained based on the concept of magnetoeleastic interactions between the core of wire and its near-surface area.
