The Tm2Fe19-xMnx (x = 0 - 1.5) and Tm2Fe16, Tm2Fe17, Tm2Fe18, Tm2Fe19 intermetallic compounds were synthesized and their magnetic and structural properties were studied. Magnetic measurements, X-ray and neutron diffraction investigations were used. The compounds crystallize in a disordered variant of the hexagonal Th2Ni17-type structure. The lattice parameters a, c increases in the Tm2Fe19-xMnx system, whereas c decreases and a increases in the Tm2Fe19 - Tm2Fe16 system as Fe content decreases. The temperatures of ferromagnetic ordering and spin-reorientation increase as Fe content decreases in these systems. Apparently, the decrease of occupation of defected dumbbell Fe (4e) site causes these regularities.

In this work, Bi[Formula: see text]SmxFe4O9 ([Formula: see text], 0.02, 0.06, 0.08, 0.1) nanoplates with an average thickness of 62–125[Formula: see text]nm were synthesized using a sol–gel method. The samples were characterized by X-ray diffraction, Fourier transform infrared spectroscopy, and scanning electron microscopy. The magnetic measurements show that the nanoplates have weak ferromagnetic ordering. The saturation magnetization of the nanoplates increases as the Sm content increases. The DC electric transport properties were studied by measuring the temperature dependence of the resistivity in the temperature range 300–680[Formula: see text]K. The materials show typical semiconductor features, and the conduction mechanisms are governed by electron and small polaron hopping in the low and high temperature measurement ranges, respectively. The Sm doping results in a significant enhancement in the electrical conductivity of the Bi2Fe4O9 nanoplates.
