Magnetocaloric effect in manganites: metamagnetic transitions for magnetic refrigeration [PDF]
, 2010 We present a study of the magnetocaloric effect in La5/8-yPryCa3/8MnO3 (y=0.3) and Pr0.5Ca0.09Sr0.41MnO3 manganites. The low temperature state of both ystems is the result of a competition between the antiferromagnetic and ferromagnetic phases.

Multi-pass cold rolling and wire drawing process of gadolinium and its magnetocaloric effect
Journal of Materials Research and Technology, 2022 Owing to low ductility of magnetocaloric material (MCM)s, the plastic deformation process is quite challenging, and information available on the deformation process of MCMs is limited. In this study, the cold rolling and wire drawing processes of Gd wire

Magnetocaloric Effect in Cu5-NIPA Molecular Magnet: A Theoretical Study. [PDF]
Materials (Basel), 2020 We calculated the magnetocaloric properties of the molecular nanomagnet Cu5-NIPA, consisting of five spins S=1/2 arranged in two corner-sharing triangles (hourglass-like structure without magnetic frustration).

Effect of Co and Fe on the inverse magnetocaloric properties of Ni-Mn-Sn [PDF]
, 2007 At certain compositions Ni-Mn-$X$ Heusler alloys ($X$: group IIIA-VA elements) undergo martensitic transformations, and many of them exhibit inverse magnetocaloric effects.
