Some changes of magnetic and micromechanical characteristics of CZ-Si crystals doped by carbon and lead after their thermal treatment in the range of 700-1100°C have been investigated. The distribution of defects formed at different annealing temperatures has been analyzed. The models for explanation of the results obtained have been proposed. A correlation between changes of magnetic susceptibility, microhardness and transformation of structural defects in crystals after their thermal treatment has been established.
