Influence of magnetic field on electric polarization in small magnetic particles

Within the framework of the phenomenological approach, we have obtained an inhomogeneous electric polarization associated with the appearance of an inhomogeneous magnetization distribution in the volume of small magnetic particles near the second-order phase transition from paramagnetic to ferromagnetic state. The temperature area of the existence of such inhomogeneous states for spherical shape particles of different sizes is determined. The change in the local electric polarization of small magnetic particles in an external magnetic field is considered.
