## Description

- description: 'BiFeO3-related perovskite-type materials attract a lot of attention
    from viewpoints of applications and fundamental science. In this work, we prepared
    two modification of heavily Mn-doped BiFeO3: BiFe0.6Mn0.4O3. A high-pressure (HP)
    modification was prepared at about 6 GPa and 1400 K. An ambient pressure (AP)
    modification was prepared by heating the HP modification at 780 K in air at AP
    (post-synthesis annealing). Crystal structures of both modifications and in-situ
    transformation were investigated with synchrotron powder X-ray diffraction. The
    transformation starts at about 700 K and finishes at about 780 K. The HP modification
    crystallizes in space group Pnma with a = 5.57956 Å, b = 15.70576 Å, c = 11.22557
    Å, and the AP modification crystallizes in space group Pbam with a = 5.63839 Å,
    b = 11.2710 Å, c = 7.75923 Å (all parameters are at room temperature). Such post-synthesis
    annealing of the HP modification (conversion polymorphism) is the only way to
    prepare the Pbam modification of the oxygen stoichiometric BiFe0.6Mn0.4O3. Magnetic
    properties of both modifications are reported. The Néel temperatures are TN =
    350 K (HP) and TN = 335 K (AP). The HP modification shows larger spin canting.
    Both modifications show negative magnetization phenomena at low temperatures in
    low magnetic fields.'
