Paramagnetic susceptibility of semiconducting CdF2:In crystals: Direct evidence of the negative-U nature of the DX-like center

Paramagnetic susceptibility κpara of CdF2 crystals with bistable In centers is measured in the temperature range T=4–300 K. For crystals cooled in the dark down to liquid helium temperature, κpara is determined by the trace Mn2+ impurity. Illumination of the sample by the ultraviolet-visible light r...
