TLDR
In this article, the magnetocaloric effect was examined for ErCo 2, which shows a first-order ferrimagnetic to paramagnetic transition at 32 K. The results strongly suggest that ErCo has a high potential for a working substance of magnetic refrigeration at 30-50 K.About:

Giant magnetocaloric effect of MnAs1-xSbx in the vicinity of first-order magnetic transition
TL;DR: The magnetocaloric effect (MCE) of Mn AS 1− x Sb x has been examined for 0⩽ x ⩽ 0.3 as discussed by the authors, where the magnetic entropy change caused by a magnetic field of Mn S 1−x Sb X reaches 25−30 J/K kg, which is about twice as large as those of conventional materials near room temperature.

Giant Magnetocaloric Effect in Gd 5 \(Si 2 Ge 2 \)
TL;DR: An extremely large magnetic entropy change has been discovered in magnetic materials when subjected to a change in the magnetic field as mentioned in this paper, which exceeds the reversible magnetocaloric effect in any known magnetic material by at least a factor of 2.
