摘要

The relaxation of nuclear magnetization in the Si-29:B crystals obeys power-law kinetics at 300 K due to direct electron-nuclear relaxation. Admixture of the exponential relaxation associated with spin diffusion was revealed at higher temperatures. The inhomogeneous distribution of linear deformation defects was revealed by electron paramagnetic resonance. This factor mainly contributes to power-law kinetics of nuclear spin relaxation.
