Abstract
35 GHz electron spin resonance signals have been obtained at 77 degrees K from CdF2:V3+, CdF2: Cr3+, PbF2: V2+, CdCl2: V2+ and impurity centres in CdF2 and PbF2. V3+ occupies a cubic site in CdF2 with g=1.940+or-0.001 and 51A=91+or-2G. Cr3+ in CdF2 occupies a cubic site with trigonal distortion arising from a Jahn-Teller effect or local interstitial fluoride compensation with g/sub ///=1.94+or-0.01, gperpendicular to =1.97+or-0.01 and b20=1.67 cm-1. The impurity centres in CdF2 and PbF2 were associated with broad line electron spin resonance signals at g=2. V2+ in CdCl2 occupied a substitutional distorted octahedral site with xy magnetic plane coincident with the cleavage planes and g/sub ///=1.974+or-0.001, 51A=51B=80+or-2G and b20=0.208 cm-1.
