| Abstract: | A study of the structure and electrical and magnetic properties of the VxMn1−x
S disordered system is reported. The existence of a low-temperature metal-insulator transition for Fermi-glass 0.4<x<0.5 compositions in paramagnetic phase, which is accompanied by a change in the structure and magnetic properties, has been
established. An analysis of the magnetic properties permits a conjecture that current carriers become delocalized in these
solid solutions at the metal-insulator transition temperature to form small ferromagnetically ordered regions (ferrons).
