Аннотация:Magnetocaloric effect (MCE) is the change in isothermal magnetic entropy (dSm) and
adiabatic temperature (dTad) that accompany magnetic transitions in materials during the application
or the removal of magnetic field under adiabatic conditions. The physics of MCE gets enriched
by correlated spin-lattice degrees of freedom. This phenomenon has been actively investigated over
the past few decades as it holds a promise for an alternate method of refrigeration/heat pumping.
This has already resulted in several reviews on this topic. This paper focusses on some recent
trends in this field and prospects of using rare-earth-based materials as active magnetic refrigerants
over a broad temperature range that includes gas liquefaction and near-room temperature
refrigeration/heating.
