Abstract

We study vanadium spinels $A$ V $_2$ O $_4$ ( $A$ = Cd, Mg) in pulsed magnetic fields up to 65 T. A jump in magnetization at $\mu_0 H \approx$ 40 T is observed in the single-crystal MgV $_2$ O $_4$ , indicating a field induced quantum phase transition between two distinct magnetic orders. In the multiferroic CdV $_2$ O $_4$ , the field-induced transition is accompanied by a suppression of the electric polarization. By modeling the magnetic properties in the presence of strong spin-orbit coupling characteristic of vanadium spinels, we show that both features of the field-induced transition can be successfully explained by including the effects of the local trigonal crystal field.
