摘要
We measured the temperature dependence of dielectric constant and striction for spinel MnT2O4 (T = V, Cr, Mn) under magnetic field. We found critical changes of the dielectric constant and striction with ferrimagnetic ordering as well as applied magnetic field in MnV2O4 and Mn3O4, which have orbital degree of freedom in the T3+ ion. This result indicates the importance of the orbital degree of freedom for the coupling between dielectric, magnetic properties and crystal structure in these spinel compounds.
