✦ Synopsis

Abstract

Thermal dependences of the magnetic susceptibility of the glass‐coated microwires with compositions Fe~3~P and SnMn prepared by the Taylor–Ulitovski method have been determined. Direct measurements of the adiabatic temperature change revealed Δ__T__~ad~ of 0.04 K in the SnMn and Δ__T__~ad~ of 0.02 K in the Fe~3~P microwires on the field change of 12 kOe. Temperatures of the peak values of MCE were found to be of ∼215 K and ∼320 K respectively. The variation of magnetic properties of the Fe~3~P wires with the change of their diameters was observed.
