| When the spin relaxation time of paramagnetic impurities at different magnetic sites differs by orders of magnitude then instead of resonance line broadening, rather a decay of the line amplitude is expected. In particular, the sp-d coupling of magnetic impurities to shallow impurities leads to a nonuniform distribution of the longitudinal relaxation rates of local spins. |
