Abstract
The correlation between the magnetic and electrical properties of the (VS)( x)(Fe2O3)(2-x) (0.9 < x < 1.25) oxysulfide solid solutions has been studied . The crossover of conductivity from the semimetallic to semiconducting typ e is accompanied by changes in the magnetic susceptibility, which are chara cteristic of the transition from delocalized to localized electrons. For x = 1.25, a region of the ferromagnetic ordering has been established in the temperature range 90-120 K. (C) 2000 MAIK "Nauka/ Interperiodica".
