Ultra-large non-volatile modulation of magnetic moments in PbZr(0.2)Ti(0.8)O(3)/MgO/La(0.7)Sr(0.3)MnO(3) heterostructure at room temperature via interfacial polarization mediation

Multiferroic hybrid structures PbZr(0.2)Ti(0.8)O(3) (PZT)/La(0.7)Sr(0.3)MnO(3) (LSMO) and PZT/MgO/LSMO were epitaxially deposited on (001) Nb:SrTiO(3) crystals. Crystallinity and ferroelectric domain structures were investigated for the PZT/LSMO heterostructure. Interestingly, relatively high non-vo...

description Multiferroic hybrid structures PbZr(0.2)Ti(0.8)O(3) (PZT)/La(0.7)Sr(0.3)MnO(3) (LSMO) and PZT/MgO/LSMO were epitaxially deposited on (001) Nb:SrTiO(3) crystals. Crystallinity and ferroelectric domain structures were investigated for the PZT/LSMO heterostructure. Interestingly, relatively high non-volatile magnetoelectric coupling effects were observed in both heterostructures at room temperature. The change of chemical valence for Mn and Ti at the PZT/MgO/LSMO interface may play a dominant role rather than external strain or orbital reconstruction, which lead to a large modulation of the magnetization. Correspondingly, the transport behavior of the PZT/MgO/LSMO heterostructure is investigated to confirm the role of oxygen vacancies motion. Our result indicates that the PZT/MgO/LSMO heterostructure have a promising application for future high-density non-volatile memories.
