Abstract

We studied EPR spectra of pure LiBaF₃ sample of high quality. For EPR measurements LiBaF₃ sample was X-irradiated at room temperature, however spectra could be observed at low temperatures - at 77 K. All hyperfine structure lines of F-type centre could be well resolved contrary to our earlier studies of Fe doped LiBaF₃ crystal. Qualitative analysis with g-tensor parameters derived from magneto-optical measurements showed that the F-type centre observed earlier by MCD-EPR techniques is the same F-type centre we observe with the EPR. We analyse origin of the hyperfine structure of the EPR spectra and their angular dependencies and discuss the structure of F-type centres in the LiBaF₃ crystal.
