Both materials reveal the characteristic low temperature dielectric relaxation obeying the Arrhenius low and assosiated with (/2-reorientations of the Li+ (100) off-centers. However, the activation energy for 6Li+ relaxation appeared to be smaller which agrees with theoretical analysis Workplace Institute of Physics Contact Kristina Potocká, potocka@fzu.cz, Tel.: 220 318 579 Year of Publishing 2005
