Abstract (EN): Magnetic and structural characteristics of ErFe O3, TmFe O3, and YbFe O3 single crystals were studied over a wide temperature range. Magnetic measurements found that the spin-rotation transitions in all crystals are well described by the earlier proposed theory with no fitting parameters. Additionally, they have shown the absence of the magnetic compensation point in TmFe O3 and a noticeable growth of the c -axis magnetization at low temperatures in TmFe O3 and ErFe O3. The x-ray measurements found no symmetry-lowering lattice distortions during the reorientation. Overall, the measurements cover a wide range of material parameters and demonstrate the generality of the modified mean field theory of the 4 ¿ 24 ¿ 2 orientation phase transitions in orthoferrites. © 2007 American Institute of Physics.
