Pressure effects on N-type ferrimagnet SmVO3

Pressure effects on N-type ferrimagnetism of SmVO3 were studied under the circumstances of 10% Ca2+-doping or about 1 GPa hydrostatic pressure. These chemical and physical pressures induced the phase transition from N- to (Q or P)-type ferrimagnetism, where N-phase shows the zero magnetization at finite compensation temperature, and (Q or P)-phase has the positive magnetization in the whole temperature range. The estimated intra- and inter-sublattice exchange integrals revealed that the SmVO3 located very near the boundary between N- and Q-phases under ambient pressure.
