The recent literature concerning the magnetocaloric effect (MCE) has been reviewed. The MCE properties have been compiled and correlations have been made comparing the behaviours of the different families of magnetic materials which exhibit large or unusual MCE values. These families include: the lanthanide (R) Laves phases (RM2, where M = Al, Co and Ni), Gd5(Si1−xGex)4 ,M n(As1−xSbx), MnFe(P1−xAsx), La(Fe13−xSix) and their hydrides and the manganites (R1−xMxMnO3, where R = lanthanide and M = Ca, Sr and Ba). The potential for use of these materials in magnetic refrigeration is discussed, including a comparison with Gd as a near room temperature active magnetic regenerator material.

Simple rules for the understanding of Heusler compounds
TL;DR: Heusler compounds as discussed by the authors are a remarkable class of intermetallic materials with 1:1:1 or 2:1-1 composition comprising more than 1500 members, and their properties can easily be predicted by the valence electron count.

Giant magnetocaloric effect driven by structural transitions
TL;DR: A phenomenological model is established that reveals the parameters essential for such a large adiabatic temperature change ΔT(ad), and it is demonstrated that obstacles to the application of Heusler alloys can be overcome by using the multi-response to different external stimuli and/or fine-tuning the lattice parameters.

Giant Magnetocaloric Effect in Gd 5 \(Si 2 Ge 2 \)

Transition-metal-based magnetic refrigerants for room-temperature applications
TL;DR: The discovery of a large magnetic entropy change is reported in MnFeP0.45As0.55, a material that has a Curie temperature of about 300 K and which allows magnetic refrigeration at room temperature, attributed to a field-induced first-order phase transition enhancing the effect of the applied magnetic field.
