Abstract

We studied the dielectric properties and strain of spinel Mn3 O4 with applied magnetic field. It was found that the dielectric constant (ε1) exhibits a large magnetic-field (H) dependence, which is anisotropic both against the direction of the magnetic field and the electric field in the magnetically ordered phases below TN =43 K. It was also found that the ε1 (H) exhibits distinctively different behaviors at three different magnetic phases. These results can be explained by the change of the orbital state of Mn3+ with the applied magnetic field due to the inverse process of single-ion spin anisotropy.
