TI3-TI SINGLE-CRYSTALS( CENTERS IN REDUCED ZNWO4)

Reduced ZnWO4:Ti single crystals were studied by ESR and ENDOR methods , which permitted characterization of a new Ti3+ centre in C-1 symmetr y (labeled as Ti3+-H). The Ti3+ ion substituted for W and showed super hyperfine interactions with two neighbouring W ions and an H impurity ion. A more detailed study of the Ti3+ (C-2) centre, whose g values we re previously published, was also achieved. The hyperfine tensor for i nteractions of the 3d(1) electron with the nuclear magnetic moments of Ti-47 and Ti-49 were determined. Copyright (C) 1996 Published by Else vier Science Ltd
