Abstract
The spinels under study are p-type semiconductors showing a change of the conductivity character from the conductive into metallic one at x ~ 0.3. An increase of the electrical conductivity with the copper concentration in a sample is linked both with the increase of the hole mobility and the hole concentration. For x ≥ 0.05 partial degeneracy of the semiconductor state is observed.
