The induced magnetization in BFO is explained by density functional theory, where the size of band gap of BFO plays an important role. Considering a classical exchange field between the LSMO and BFO layers, we further show that magnetization is expected to extend throughout the BFO, which provides a theoretical explanation for the results of the neutron scattering experiment. © 2014 American Physical Society.}, year = {2014}, journal = {Physical Review Letters}, volume = {113}, number = {4}, publisher = {American Physical Society}, issn = {00319007}, doi = {10.1103/PhysRevLett.113.047204}, note = {cited By 46}, language = {eng}, }
