Magnetothermal Properties of Heavy Rare Earth Metals and Fe–Rh-Based Alloys

The review is devoted to theoretical–experimental studies of the magnetothermal properties of several classes of magnetic materials: heavy rare earth metals and a family of binary and three-component alloys based on iron and rhodium. The results of calculations of properties from first principles, the self-consistent (mean) field model, empirical and ad hoc models, and numerical simulation methods are presented and analyzed. As well, numerous experimental data are presented: direct determination of the magnetocaloric effect (MCE), measurement of magnetic characteristics (field and temperature dependences of magnetization and magnetic susceptibility), measurement of temperature dependences of heat capacity, differential calorimetry, Hall magnetometry, EXAFS spectroscopy, scanning and transmission electron microscopy.
