在Y型六方铁氧体Ba2Mg2Fe12O22中发现铁电极化和自发磁化同时存在。低于 ∼0.02 T 的小磁场引起的磁化反转伴随着通过亚铁磁和铁电畴壁的夹紧而发生的电极化反转。这种行为可以潜在地用作磁可重写铁电存储器和电可重写磁存储器。
Coexistence of the ferroelectric polarization and spontaneous magnetization has been found in Y-type hexaferrite Ba2Mg2Fe12O22. The reversal of magnetization by a small magnetic field below ∼0.02 T 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.
