Investigation of the Bonding of Iron‐Group Ions in Fluoride Crystals. II

This paper describes an ESR investigation of the bonding of iron‐group ions with the configurations d6(Fe2+) and d7(Fe+, Co2+, Ni3+) on cubic lattice sites in the crystals LiF, NaF, and KMgF3. To aid the analysis of the bonding of d7 ions, the optical absorption spectrum of Co2+ was measured in LiF and KMgF3. A discussion is given of the effects of lattice dimensions and the charge state of the impurity ion on the bonding parameters.
