Abstract:

Results are presented of an EPR study of theO(-) hole center in LiB3O5 (lithium triborate) crystals. Analysis of angular dependences of EPR spectra is used to determine the principal values of the g tensor (g(XX) = 2.032, g(YY) = 2.020, g(ZZ) = 2.007), along with the modulus of the isotropic part of the A(2) tensor (\textbackslash{}A\textbackslash{} = 12.2 G) and the orientations of the principal axes of the paramagnetic O- center. The most probable model for the O- center in lithium berate crystals is the following: a hole trapped by the center is localized on ap-orbital of an oxygen ion linking two boron atoms with coordination numbers three and four near a negatively charged stabilizing structural defect. In this case the characteristic hyperfine splitting is due primarily to the interaction of the unpaired electron spin with the B-11 nucleus. (C) 1997 American Institute of Physics.
