“…It was announced, that the mentioned mechanism probably can explain some experimental results. In [9] it was noted, that the second kind relaxation, induced by a mechanism, similar to that discussed in [1] (with the difference, that the modulation of constants of dipole±dipole interaction between paramagnetic impurity spins is caused by TLS, instead of phonons), is not effective.…”

“…[6,7], new TLS relaxation mechanisms caused by the existence of nuclear quadrupole moments were discussed. Later, in papers [9,10], the first kind relaxation induced by the modulation of dipole±dipole constants of interaction between matrix nuclear spins and electronic spins of impurities (which cause TLS tunneling from one to the other side of the potential well), was investigated. It was announced, that the mentioned mechanism probably can explain some experimental results.…”

The low temperature nuclear spin±lattice relaxation mechanism caused by the effective interaction between nuclear spins and two-level systems (TLS), arising from a paramagnetic centre interaction with TLS by means of g-factor modulation and the electron±nuclear dipole±dipole interaction, is investigated. It is shown, that this mechanism of the nuclear spin±lattice relaxation is effective under definite conditions.
