We report on the interfacial magnetic coupling in manganite bilayers of collinear ferromagnetic La0.7 Sr0.3 MnO3 and noncollinear multiferroic TbMnO3. Exchange bias is observed at the Néel temperature of TbMnO3 (∼41 K) due to the onset of long-range antiferromagnetic ordering in the Mn spin sublatti...
