Abstract

The nature of paramagnetic centers formed in Cz‐Si monocrystals after their high‐temperature treatment in the temperature range of 650–1100 °C and repeated high‐temperature treatment at 1150 °C are studied. The regions of increase and decrease of paramagnetic center concentration are determined by means of the measurements of magnetic susceptibility (MS). It is found that the MS changes observed experimentally are attributed to the generation of oxygen‐related clusters and dislocation loops. The amount of impurity‐structural complexes in these crystals is investigated by the XRD method. The radii and concentration of clusters and dislocation loops are determined.
