Lattice vibrations of α′-NaV2O5
We have measured far infrared reflectance and transmittance spectra as well as Raman scattering spectra of α′-NaV2O5 single crystals for all the principal polarizations. The temperature range above the phase tran...

Hyperfine structure of submillimeter EPR spectra of non-Kramers lanthanide ions in crystals
The hyperfine structures of submillimeter EPR spectra of CsCdBr3:Tm3+ and CaF2:Dy2+ single crystals have been resolved and analyzed. The crystal field parameters and the magnetic hyperfine constants are obtained ...

Submillimeter electron-nuclear excitation spectra in CsCdBr3:Ln3+ (Ln=Tm, Ho) crystals
The ESR spectra of single and pair impurity centers of thulium and holmium ions in CsCdBr3:Tm3+ and CsCdBr3:Ho3+ crystals are measured in the frequency range 160-400 GHz. Analysis of the characteristic features o...
