Structural and Magnetic Phase Transitions in BiFe_{1 - x}Mn_xO₃ Solid Solution Driven by Temperature.

ABSTRACT: The crystal structure and magnetic state of the (1 - x)BiFeO₃-(x)BiMnO₃ solid solution has been analyzed by X-ray diffraction using lab-based and synchrotron radiation facilities, magnetization measurements, differential thermal analysis, and differential scanning calorimetry. Dopant concentration increases lead to the room-temperature structural transitions from the polar-active rhombohedral phase to the antipolar orthorhombic phase, and then to the monoclinic phase accompanied by the formation of two-phase regions consisting of the adjacent structural phases in the concentration ranges 0.25 < x₁ < 0.30 and 0.50 ≤ x₂ < 0.65, respectively. The accompanied changes in the magnetic structure refer to the magnetic transitions from the modula
