Abstract

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 (M_r) and coercive field (H_c) 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.
