Abstract :
Ca2+-doping effects were studied on the N-type ferrimagnet of NdVO3. The chemical pressures by Ca2+-doping induced lowering of ferrimagnetic transition temperature Tc and compensation temperature θc, resulting in the phase transition from N- to P-type ferrimagnetic phase. In the N-phase, spontaneous magnetization Msp becomes zero at finite temperature θc and in the P-phase, Msp is positive in whole temperature range. It was revealed that NdVO3 and Ca0.1Nd0.9VO3 located in the N-phase and Ca0.2Nd0.8VO3 in the P-phase. This N→P transition by the chemical pressure was discussed by the intra- and inter-sublattice exchange integrals estimated from the molecular field approximation.
