Thermal, magnetic and photoelectrical behaviors of sillenite Bi25FeO39 microcrystals

Comparison of the structure–property relationships between sillenite and perovskite phases of Bi0.9Dy0.1FeO3 nanostructures

“…However, due to the magnetically disordered surface spins, the M–H loops remained unsaturated under the 7 T applied field with magnetization values identified as 18, 19, 19, and 29 emu per gm at the temperatures of 300, 100, 50, and 5 K, respectively. 66 Unlike the HT-synthesized BDFO sample, within a temperature range of 50–300 K, the SG-synthesized BDFO sample demonstrated hysteresis loops with a small but non-zero coercivity and remanent magnetization (Fig. 7(b)).…”

Role of Cr Doping on the Structure, Electronic Structure, and Electrochemical Properties of BiFeO3 Nanoparticles

“…This pattern shows the sharp peaks indicating the polycrystalline nature of the nanoparticles. The initial identification of the peaks was performed by matching with the standard peak positions corresponding to the JCPDS card numbers: 71-2494 for pure BiFeO 3 and 77-0865 for Bi 25 FeO 39 , as displayed in Figure 1b,c [24]. This reveals the presence of two phases in the samples: one, BiFeO 3 as the primary phase, and the second, Bi 25 FeO 39 as the secondary.…”

“…Generally, the BiFeO 3 phase is accompanied by secondary phases-Bi 2 Fe 4 O 9 , Bi 25 FeO 39 , etc. [8,24,25]. Suppressing the secondary phases is a quite challenging task.…”
