- Аннотация: The field and temperature dependences of the magnetization (fields B<7.5 T, temperatures T=2.0−75 K) of the samples from a Pb1−x−ySnxVyTe (x=0.08, y=0.01) single crystal ingot, synthesized by the Bridgman method, are studied. It is established that magnetization of the samples has two main contributions: paramagnetism of vanadium ions and diamagnetism of the crystal lattice. The field and temperature dependences of the magnetization was fitted by a sum of modified Brillouin functions, corresponding to the paramagnetic contributions of vanadium ions in two different charge states, and the linear in field diamagnetic contribution. In the framework of the model assuming the electronic structure rearrangement of the alloys with doping, the concentrations of vanadium ions in two different magnetic states and nature of their changes along the ingot are determined. Comparison of the obtained results with the data of X-ray fluorescence microanalysis and the results of the study of the galvanomagnetic properties of the samples was done.
