Low magnetic field reversal of electric polarization in a Y-type hexaferrite
, 2011 Magnetoelectric multiferroics in which ferroelectricity and magnetism coexist have attracted extensive attention because they provide great opportunities for the mutual control of electric polarization by magnetic fields and magnetization by electric ...

Impurity effects in multiferroic compounds [PDF]
arXiv, 2009 We investigate the effect of impurities in multiferroic materials using an equation of motion approach for the spin dynamics of the host multiferroic compound. We model the impurities as a two-level system and focus on the regime where the impurity spins relax slowly.
