Magnetic properties ofLaVO3

Abstract

Herein, we report on the magnetic properties of ${\mathrm{LaVO}}_3$. We have observed diamagnetism in this compound, which is an antiferromagnetic insulator, below the Néel temperature under field-cooled conditions. We observe hysteresis in magnetization versus applied field M(H) isotherms below the Néel temperature. ${\mathrm{LaVO}}_3$ has a ferromagnetic component to the spin ordering, due to canting of spins and/or due to ferrimagnetism. Four-probe resistivity measurements rule out the possibility of superconductivity and the dimagnetism appears to be associated with uncompensated antiferromagnetism (ferrimagnetism). From our ${}_{}{}^{51}{}_{}{}^{}\mathrm{V}$ NMR measurements on ${\mathrm{LaVO}}_3$ we associate the kink in susceptibility with magnetic ordering.
