Abstract

Coexistence of the ferroelectric polarization and spontaneous magnetization has been found in Y-type hexaferrite Ba₂Mg₂Fe ₁₂C₂₂. The reversal of magnetization by a small magnetic field below ∼0.02T accompanies an electric polarization reversal through the clamping of ferrimagnetic and ferroelectric domain walls. This behavior can be potentially used as a magnetically rewritable ferroelectric memory and an electrically rewritable magnetic memory.
