摘要：

The crystal structure and magnetic properties of the Bi1 - x Ca (x) Fe1 - x/2Nb O-x/2(3) system were studied. It is shown that, at x a parts per thousand currency sign 0.15, the unit-cell symmetry of solid solutions is rhombohedral (space group R3c). Solid solutions with x a parts per thousand yen 0.3 have an orthorhombic unit cell (space group Pbnm). The rhombohedral compositions are antiferromagnetic, while the orthorhombic compositions exhibit a small spontaneous magnetization due to Dzyaloshinski&Aumlaut--Moriya interaction. In CaFe0.5Nb0.5O3, the Fe3+ and Nb5+ ions are partially ordered and the unit cell is monoclinic (space group P2(1)/n). In the concentration range 0.15 < x < 0.30, a two-phase state (R3c + Pbnm) is revealed.
