Abstracts

Bilayered epitaxial BiFeO_3/YBa_2Cu_3O_7 films were fabricated on (100) [(LaAlO_3)_{0.3}(Sr_2TaAlO_6)_{0.7}] substrates by sputtering method. For structural comparison the bilayered BiFeO_3/La_{0.67}Sr_{0.33}MnO_3 films were also deposited on (100) SrTiO_3 substrates. A weak ferromagnetic moment is observed in BiFeO_3/YBa_2Cu_3O_7 films. The mechanism responsible for weak ferromagnetic moment arises presumably from the epitaxy strain induced canted antiferromagnetic structure.
