“…And last but not the least, magnetisation is highly sensitive to impurities and phase inhomogeneity. As it was shown previously by XRD and XPS analysis, the experimental samples contain Bi 2 Fe 4 O 9 and Bi 2 O 3 by-phases with a different magnetization behavior 79 – 81 , which form inhomogeneous structures in combination with BFO and BReFO phases. However, despite significant paramagnetic-like components, the saturation magnetisation of the ferromagnetic part of the reported hysteresis loop for Bi 2 Fe 4 O 9 was not higher than 0.3 emu/g.…”

“…pbam) с параметрами a = 7.9 ¦ , b = 8.4 ¦ и c = 6.0 ¦ (Z = 2), в которой атомы железа локализуются в кислородных октаэдрах FeO 6 и тетраэдрах FeO 4 [5]. Спины железа в октаэдрах взаимодействуют по ферромагнитному типу, а в тетраэдрах антиферромагнитно связаны между собой и спинами железа в октаэдрах [6,7]. Ниже комнатной температуры объемный Bi 2 Fe 4 O 9 является антиферромагнетиком с температурой Нееля T N = 237−265 K [7,8].…”

Ниже комнатной температуры объемный Bi 2 Fe 4 O 9 является антиферромагнетиком с температурой Нееля T N = 237−265 K [7,8]. В керамических образцах отмечается наличие примесных фаз, которые могут влиять на магнитное поведение материала [8][9][10].…”
