PARAMAGNETIC PROPERTIES OF THE ALKALINE EARTH FLUORIDES.

Abstract

The results of a program concerned with the paramagnetic properties of the alkaline earth fluorides are summarized. A 3 cm wavelength electron spin resonance absorption spectrometer was constructed. The experimental portion of the program was mainly concerned with the investigation of the paramagnetic properties of isolated impurity ions in the alkaline earth fluorides as a function of temperature. In particular, the hyperfine coupling constants for Mn(2+) in CaF2 and SrF2 were measured over the temperature range 77 to 850K. In both cases the magnitude of the hyperfine coupling constant decreases with increasing temperature; and the temperature dependance is stronger for SrF2. The results have been interpreted using the Simanek-Orbach theory of a phonon-induced hyperfine field. (Author)
