Magnetocaloric effect in nanogranular glass coated microwires

Thermal dependences of the magnetic susceptibility of the glass-coated microwires with compositions Fe3P and SnMn prepared by the Taylor–Ulitovski method have been determined. Direct measurements of the adiabatic temperature change revealed ΔTad of 0.04 K in the SnMn and ΔTad of 0.02 K in the Fe3P 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 Fe3P wires with the change of their diameters was observed.
