Zero-field studies of spin-lattice relaxation processes in non-Kramers doublet of LiF:Ni super(2+)

We use the inversion recovery technique with electron-spin-echo detection in order to study the non-resonant cross-relaxation of Ni super(2+)-V sub(Li) with a faster relaxers-the exchange-coupled clusters of Ni super(2+) ions. An analysis of the results revealed a very high relaxation rate in non-Kr...

Description
Summary:We use the inversion recovery technique with electron-spin-echo detection in order to study the non-resonant cross-relaxation of Ni super(2+)-V sub(Li) with a faster relaxers-the exchange-coupled clusters of Ni super(2+) ions. An analysis of the results revealed a very high relaxation rate in non-Kramers doublet of LiF:Ni super(2+). The effect of a magnetic field on the spin-lattice relaxation of Ni super(2+) 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).
