Abstract

A significant narrowing of the electron paramagnetic resonance (EPR) and additional hyperfine structures of lithiumoxygen (LiO) centers was observed in isotopically enriched ²⁸Si single crystals. Unexpected splitting was found, reflecting the principal axis of the formally assigned trigonal g-tensors being tilted 3° from the 〈111〉 crystal axis, i.e., the g-tensor of the LiO center actually has a monoclinic symmetry. Furthermore the splitting of the ⁷Li hyperfine lines into four components was observed at a temperature of 3.5 K.
