The xBiCoO3-(1-x)BiFeO3 [0≤x≤58 at. ] solid solution films were epitaxially grown on SrTiO3 (100) substrates, and the dependence of the magnetic properties on the BiCoO3 concentration was systematically investigated. The remanent magnetization (Mr) and coercive field (Hc) increased with the BiCoO 3 in the case of rhombohedral composition (x≤18 at. %), and it maximally enhanced at morphotropic phase boundary (MPB) (20≤x≤25 at %). The magnetization decreased in the case of a tetragonal structure (30 at %≤ x). The magnetoelectric (ME) effect at room temperature expect to observe for the BiCoO3-BiFeO3 solid solution films in the case of the rhombohedral structure and for MPB.
