Abstract
It has been found that the number of paramagnetic clusters formed during plastic deformation of silicon crystals increases in crystals enriched with the 29Si isotope. It has been shown that there are antiferromagnetic spin-spin couplings with energies of ∼30–50 K in deformation-induced clusters of paramagnetic defects. The effect of the hyperfine interaction on spin-dependent reactions of silicon with oxygen or changes in elastic constants and lattice dilatation can cause the formation of deformation-induced defects in crystals enriched with 29Si.
