On the Structure of α‑BiFeO₃

Polycrystalline and monocrystalline α-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 α-BiFeO_3. The present data show that α-BiFeO₃ crystallizes in space group <i>P</i>1 with <i>a</i> = 0.563 17(1) nm, <i>b</i> = 0.563 84(1) nm, <i>c</i> = 0.563 70(1) nm, α = 59.33(1)°, β = 59.35(1)°, γ = 59.38(1)°, and the magnetic structure of α-BiFeO₃ can be described by space group <i>P</i>1 with magnetic modulation vector in reciprocal space <b>q</b> = 0.0045<b>a</b>* – 0.0045<b>b</b>*, which is the magnetic structure model proposed by I. Sosnowska applied to the new <i>P</i>1 crystal symmetry of α-BiFeO₃
