PARAMAGNETIC RESONANCE SPECTRUM OF DIVALENT IRON IN ZINC FLUOSILICATE

Abstract

An anisotropic absorption edge observed at low temperatures in the e.s.r. spectrum of Fe(tt) in zinc fluosilicate is attributed to a forbidden (delta M = 2) transition within an excited doublet. The measured value, g = 2.38, is interpreted in terms of a trigonal crystalline field component some four times smaller than that deduced from susceptibility measurements on the undilute ferrous salt. Confirmation is obtained from measurements made in the perpendicular plane where the doublet is split by a second-order Zeeman effect. The results of experiments on mixed Fe-Zn crystals point tentatively to a gradual variation of trigonal ield strength with Fe(tt) concentration. (Author)
