Magnetic field tuning of polaron losses in Fe doped BaTiO3 single crystals

, 2012
Artificial tuning of dielectric parameters can result from interface conductivity in polycrystalline materials. In ferroelectric single crystals, it was already shown that ferroelectric domain walls can be the source of such artificial coupling.
