文摘

Polycrystalline and monocrystalline 伪-BiFeO₃ crystals have been synthesized by solid state reaction and flux growth method, respectively. X-ray, neutron, and electron diffraction techniques are used to study the crystallographic and magnetic structure of 伪-BiFeO_3. The present data show that 伪-BiFeO₃ crystallizes in space group P1 with a = 0.563鈥?7(1) nm, b = 0.563鈥?4(1) nm, c = 0.563鈥?0(1) nm, 伪 = 59.33(1)掳, 尾 = 59.35(1)掳, 纬 = 59.38(1)掳, and the magnetic structure of 伪-BiFeO₃ can be described by space group P1 with magnetic modulation vector in reciprocal space q = 0.0045a* 鈥?0.0045b*, which is the magnetic structure model proposed by I. Sosnowska(1) applied to the new P1 crystal symmetry of 伪-BiFeO₃.
