EPR and optical spectra of Yb3+ in CsCdBr3: Charge-transfer effects on the energy-level structure of Yb3+ in the symmetrical pair centers

Malkin B.; Leushin A.; Iskhakova A.; Heber J.; Altwein M.; Moller K.; Fazlizhanov I.; Ulanov V. (2000)

Electron paramagnetic resonance (EPR), optical absorption, fluorescence, and excitation spectra of CsCdBr3:1% Yb3+ single crystals were taken at 4.2 K. An analysis of the dependence of the EPR spectrum on the magnetic-field ...
Far-infrared spectroscopy investigation and lattice dynamics simulations in CsCdBr3 and CsCdBr3: R3+ crystals

Malkin B.; Iskhakova A.; Kamba S.; Heber J.; Altwein M.; Schaack G. (2001)

Polarized infrared reflectivity spectra of CsCdBr3 crystal were measured at temperatures 20 and 300 K in the wave number range of 10-650 cm-1. Frequencies and damping of the optically active lattice modes at the Brillouin ...
Hyperfine structure of submillimeter EPR spectra of non-kramers lanthanide ions in crystals

Shakurov G.; Tarasov V.; Malkin B.; Iskhakova A.; Kasatkina L.; Heber J.; Altwein M. (1998)

The hyperfme 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 from fitting ...
