Abstract:

The averaging of a part of spin packets for two transitions of the Gd3+ trigonal center in ferroelectric lead germanite in the vicinity of coincidence of their positions leading to the emergence of an additional EPR signal is investigated. A computer simulation of the experimental spectrum gives the temperature dependence of the spin-lattice relaxation time connecting the doublets in which resonance transitions occur and leading to selective averaging of the packets. An increase in the relaxation rate for intra- and interdoublet transitions is observed in the vicinity of the structural ferroelectric transition. (C) 2002 MAIK ``Nauka/Interperiodica{''}.
