Effect of Magnetic Field on Electric Polarization in Small Magnetic Particles

Within the framework of a phenomenological approach, inhomogeneous electric polarization was induced in small magnetic particles due to the appearance of an inhomogeneous magnetization distribution in their bulk near the second-order phase transition from paramagnetic to ferromagnetic state. The temperature range of the existence of such inhomogeneous states for spherical shape particles of different sizes was determined. The change in the local electric polarization of small magnetic particles in an external magnetic field was considered.
