摘要：
Herein, we report on the magnetic properties of LaVO3. We have observed diamagnetism in this compound, which is an antiferromagnetic insulator, below the Neel temperature under field-cooled conditions. We observe hysteresis in magnetization versus applied field M(H) isotherms below the Neel temperature. LaVO3 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 V-51 NMR measurements on LaVO3 we associate the kink in susceptibility with magnetic ordering.
