Theoretical analysis of magnetic properties and the magnetocaloric effect using the Blume-Capel model

Condensed Matter Physics, 2022
This work investigates the magnetic properties and the magnetocaloric effect in the spin-1 Blume-Capel model. The study was carried out using the mean-field theory from the Bogoliubov inequality to obtain the expressions of free energy, magnetization and

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
