Electronic structure and magnetic properties of diluted magnetic semiconductors Pb1-XVXTe
The galvanomagnetic effects, the temperature and magnetic field dependences of mag- netization and electron paramagnetic resonance (EPR) in the Pb1-xVxTe (x ≤ 0.02) alloys under variation of the alloy composition have been investigated. Low temperature activation range of the impurity conductivit...

| description |
The galvanomagnetic effects, the temperature and magnetic field dependences of mag-
netization and electron paramagnetic resonance (EPR) in the Pb1-xVxTe (x ≤ 0.02) alloys under
variation of the alloy composition have been investigated. Low temperature activation range of
the impurity conductivity on the temperature dependences of the resistivity and the Hall coefficient has been revealed and attributed to the appearance of vanadium-induced deep level in the
gap of the alloys. The magnetic susceptibility was found to be a superposition of the matrix
diamagnetism and Curie-Weiss paramagnetism provided by vanadium impurity ions. EPR
spectra were measured and the g-factor in the temperature range 85-200 K was obtained.
