研究了DyVO 3单晶中不同自旋轨道有序态之间的临界相竞争。随着温度的降低，该化合物表现出可重入的自旋和轨道有序（SO和OO）转变：SO的C-->G-->C型和OO的G-->C-->G型。有人发现，磁场也驱动从C到G的OO和伴随着从G到C的SO，其中后者是耦合的Dy 4f时刻的变磁过渡的相变。讨论了这种新的磁场诱导轨道转换的机制。
The critical phase competition between different spin-orbital-ordered states has been investigated for the DyVO3 single crystal. As temperature is lowered, the compound exhibits a reentrant spin and orbital ordering (SO and OO) transition: C-->G-->C type for SO and G-->C-->G type for OO. It was found that a magnetic field also drives the phase transition from C to G for OO and concomitantly from G to C for SO, the latter of which is coupled with the metamagnetic transition of the Dy 4f moments. The mechanism of this novel magnetic-field-induced orbital switching is discussed.
