Summary: The phase analysis, site occupancy, and hyperfine fields of Mn1-xCoFexGe alloys (x = 0.01, 0.02, 0.05, 0.10) after annealing were studied using Mössbauer spectroscopy. The compounds were found to have two phases of Ni2In type hexagonal structure and TiNiSi type orthorhombic structure. The lattice parameters and unit cell volume were not significantly affected by the Fe concentration in both phases. The Mössbauer spectra consisted of two doublets from Fe in the hexagonal structure and two broad sextets from Fe in the orthorhombic structure. The induced hyperfine magnetic field in the hexagonal structure was higher for Fe at Mn sites than for Fe at Co sites. The magnetic moments of Fe were found to align along the external magnetic field direction with similar values.

Summary: This study reports the solid-state synthesis features, thermal behavior, dielectric and magnetic properties of single phase ceramic material based on the nine-layered Aurivillius phase, Bi10Fe6Ti3O30. The optimal synthesis conditions, sintering and decomposition temperatures were determined, along with the phase formations and morphology studies. Significant differences in magnetic behavior between the nine-layered phase and other BFTOs Aurivillius phases were observed due to an increase in bismuth orthoferrite content in the perovskite-like block of the compound.

Summary: The magnetic properties and Mo & BULL;ssbauer spectra of the Y1.8Bi1.2Fe3.5Ga1.5O12 compound were studied. The temperature dependence of the saturation magnetization, hysteresis, and coercive field stability in the magnetically ordered state were found to be linear. The distribution of iron ions and the concentration of paramagnetic iron ions were determined using Mo & BULL;ssbauer measurements. Two critical temperatures - the sublattice magnetization compensation temperature and the ferrimagnet-paramagnet transition temperature - were established. The disappearance of the phonon mode near the magnetic transition was observed. The experimental data were interpreted using the spin-lattice interaction model.

Summary: In this study, a composite electrode composed of Ti/TiH2/beta-PbO2_Mn3O4@C was fabricated and investigated for zinc electrowinning. The composite electrode exhibited low overpotential, Tafel slope, icorr, and high voltage stability, outperforming most reported Ti-based PbO2 electrode materials. The excellent catalytic activity can be attributed to the low resistance and porous interlayer of TiH2 nanosheets, as well as the addition of Mn3O4@C micro-flakes to the active layer.
