Abstract

A direct method was used to study the magnetocaloric effect (MCE) for samples of the compound Mn5Si3 under adiabatic conditions in magnetic fields up to 2 T at cryogenic temperatures in the range from 25 to 125 K. According to the results of measurements, it is shown that at temperatures near the first-order metamagnetostructural phase transition from a noncollinear antiferromagnetic to a collinear antiferromagnetic state, both inverse and сonventional MCE are observed. The maximum value of the inverse MCE was ΔTad = –0.27 K at initial temperature T0 = 55 K in a magnetic field of 2 T. Conventional MCE with maximum value ΔTad = +0.23 K is observed at T0 = 70 K in a field of 2 T.
