Abstract

A theoretical and experimental evaluation of the experimental method for determining the magnetocaloric properties of magnetic materials show that the magnetic field heat capacity data can provide a reliable results, which may be used for a detailed analysis of the thermodynamic cycle efficiency. In addition the magnetocaloric effect and the magnetic field induced magnetic entropy change determined from the magnetic field dependence of the heat capacity has an accuracy that is equal to or better than that obtained from other methods — direct and magnetization measurements.
