Magnetoelectric effect in doped magnetic ferroelectrics

Magnetoelectric effect in doped magnetic ferroelectrics We propose a model of magnetoelectric effect in doped magnetic ferroelectrics. This magnetoelectric effect does not involve the spin-orbit coupling and is based purely on the Coulomb interaction. We calculate magnetic phase diagram of doped magnetic ferroelectrics. We show that magnetoelectric coupling is pronounced only for ferroelectrics with low dielectric constant. We find that magnetoelectric coupling leads to modification of magnetization temperature dependence in the vicinity of the ferroelectric phase transition. A peak of magnetization appears. We find that magnetization of doped magnetic ferroelectrics strongly depends on the applied electric field. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Physical Review B American Physical Society (APS)
