Inverse magnetocaloric effect in polycrystalline La$_{0.125}$Ca$_{0.875}$MnO$_{3}$

TL;DR

This paper reports the observation of the inverse magnetocaloric effect in polycrystalline La$_{0.125}$Ca$_{0.875}$MnO$_{3}$, attributed to antiferromagnetic stabilization and magnetic inhomogeneity, a rare phenomenon in manganites.

Contribution

First demonstration of inverse magnetocaloric effect in this specific manganite compound, linking it to magnetic phase inhomogeneity.

Findings

Inverse magnetocaloric effect observed in La$_{0.125}$Ca$_{0.875}$MnO$_{3}$

Effect attributed to stabilization of antiferromagnetic phase

Highlights rare manifestation in manganites

Abstract

Recently the inverse magnetocaloric effect is observed for different compounds. However there is very rare for any manifestation of the effect to be seen in manganites. We have found inverse magnetocaloric effect in the case of polycrystalline La$_{0.125}$Ca$_{0.875}$MnO$_{3}$. Such phenomenon is attributed to the stabilization of antiferromagnetic state associated with inherent magnetic inhomogeneous phases for this compound.
