摘要：

FeV2O4 with orbital degrees of freedom both at the Fe2+ and V3+ ions exhibits successive structural phase transitions. We studied this structural and magnetic properties as well as the correlation between the two. We found that the crystalline domains in the tetragonal or orthorhombic phases can be aligned by the applied magnetic field, inducing a large magnetostriction (similar to 1%). The competition and cooperation of Fe2+ and V3+ orbitals is the possible origin of these intriguing properties in FeV2O4.
