O. Kanert et al., NATURE OF UNCOMMON NUCLEAR-SPIN RELAXATION IN NACL WITH HIGH-CONCENTRATION OF REORIENTING OH-IMPURITIES AT LOW-TEMPERATURES, Radiation effects and defects in solids, 134(1-4), 1995, pp. 337-339
The unusual features of low temperature nuclear spin relaxation in NaC
l with high concentration of reorienting OH- impurities, with its prim
arily uncommon temperature and electric field dependencies, are explai
ned in the framework of a model based on cooperative OH- dipole relaxa
tion with taking into account the role of critical dipole-dipole clust
ers.
