Magnetocaloric and hysteretic properties of Ni-Mn based Heusler alloys

Abstract

The aim of this work is the comprehensive characterization of the magnetocaloric effect of Heusler alloys using different measurement techniques like calorimetry, magnetometry and the direct determination of the adiabatic temperature change in order to combine them in the S(T) diagram. It turns out that some discrepancies can appear when comparing measurements obtained with different speeds.
