Abstract
When the spin relaxation time of paramagnetic impurities at different magnetic sites differs by orders of magnitude then instead of resonanc e line broadening, rather a decay of the line amplitude is expected. I n particular, the sp-d coupling of magnetic impurities to shallow impu rities leads to a nonuniform distribution of the longitudinal relaxati on rates of local spins.
