【 摘 要 】
We consider phase-separated states in magnetic oxide (MO) thin films. We show that these states have a nonzero electric polarization. Moreover, the polarization is intimately related to a spatial distribution of magnetization in the film. Polarized states with opposite polarization and opposite magnetic configuration are degenerate. An external electric field removes the degeneracy and allows one to switch between the two states. So, one can control electric polarization and magnetic configuration of the phase-separated MO thin film with the external electric field.
