BiFeO3/La0.7Sr0.3MnO3 heterostructures deposited on Spark Plasma Sintered LaAlO3 Substrates
D. Pravarthana, M. Trassin, Jiun Haw Chu +5
Multiferroic BiFeO3 (BFO) / La0.7Sr0.3MnO3 heterostructured thin films were grown by pulsed laser deposition on polished spark plasma sintered LaAlO3 (LAO) polycrystalline substrat…
Tuning the Competition between Ferromagnetism and Antiferromagnetism in a Half-doped Manganite through Magnetoelectric Coupling
Di Yi, Jian Liu, Satoshi Okamoto +6
We investigate the possibility of controlling the magnetic phase transition of the heterointerface between a half-doped manganite LaCaMnO and a multiferroic B…
Magnetic interaction at an interface between manganite and other transition metal oxides
Satoshi Okamoto
A general consideration is presented for the magnetic interaction at an interface between a perovskite manganite and other transition metal oxides. The latter is specified by the e…
Interface ferromagnetism and orbital reconstruction in BiFeO3- La0.7Sr0.3MnO3 heterostructures
P. Yu, J. -S. Lee, S. Okamoto +14
We report the formation of a novel ferromagnetic state in the antiferromagnet BiFeO3 at the interface with La0.7Sr0.3MnO3. Using x-ray magnetic circular dichroism at Mn and Fe L2,3…
Nanoscale control of exchange bias with BiFeO3 thin films
Lane W. Martin, Ying-Hao Chu, Mikel B. Holcomb +5
We demonstrate a direct correlation between the domain structure of multiferroic BiFeO3 thin films and exchange bias of Co0.9Fe0.1/BiFeO3 heterostructures. Two distinct types of in…
