Concentration dependence of EPR spectra in mixed (BaF2)1 - x(CeF3)x crystals

Abstract

In the EPR spectra of the (BaF2)1 - x(CeF3)x system, additional lines appear as the concentration x in the mixture increases from 10-3 to 10-2, some of which correspond to tetragonal centers with g{norm of matrix} = 0. 725 and g⊥ = 2. 52. These lines are similar to those detected previously in mixed (BaF2)1 - x - y(CeF3)x(LaF3)y systems with a low cerium concentration (x ≈ 10-3) and in the CaF2: Ce3+ crystal grown with added Na+ ions. © 2013 Pleiades Publishing, Ltd.
