We use the inversion recovery technique with electron-spin-echo detection in order to study the non-resonant cross-relaxation of Ni2+–VLi with a faster relaxers—the exchange-coupled clusters of Ni2+ ions. An analysis of the results revealed a very high relaxation rate in non-Kramers doublet of LiF:Ni2+ The effect of a magnetic field on the spin–lattice relaxation of Ni2+ has
estimated by comparing the results obtained for non-Kramers doublet around zero-magnetic field and for resonance at ~ 394 mT (X-band microwave frequency).
