We present an experimental study of the Dynamic Nuclear Polarization (DNP) of 29Si nuclei in silicon crystals of natural abundance doped with As in the temperature range 0.1-1 K and in a strong magnetic field of 4.6 T. This ensures a very high degree of electron spin polarization, extremely slow nuclear relaxation and optimal conditions for realization of Overhauser and resolved solid effects. We found that the solid effect DNP leads to the appearance of a pattern of holes and peaks in the ESR…

DYNAMIC ORIENTATION OF NUCLEI BY FORBIDDEN TRANSITIONS IN PARAMAGNETIC RESONANCE
Principally from the viewpoint of orienting radionuclei, this paper considers magnetically dilute paramagnetic ions in crystals for various cases in which there is a nonnegliable radio-frequency
Nuclear Spin Diffusion Induced by Paramagnetic Impurities in Nonconducting Solids
It is shown that paramagnetic impurities can induce nuclear spin diffusion in nonconducting solids. The component of the impurity spin along the external magnetic field (assumed to be the $z$ axis),
