Description

The magnetic entropy change of Fe3−xMnxSi (for x=1.15, 1.3 and 1.5) has been extracted from isothermal magnetization measurements near the Curie temperature. We used the scaling hypotheses of the thermodynamic potentials to scale the magnetic entropy change to a single universal curve for each sample. The effect of the exchange field and the Curie temperature on the maximum entropy change is discussed. - Highlights: • The maximum of the magnetic entropy change occurs at temperatures T>TC. • The exchange field enhances the magnetic entropy change. • The magnetic entropy change at TC is inversely proportional to TC. • Scaling hypothesis is used to scale the magnetic entropy change
