Abstract
The magnetic circular dichroism (MCD) for all transitions within cubic centres in cubic crystals is shown to be independent of the orientation of the crystal at high temperatures. At low temperatures, where the C-type term is no longer linearly dependent on magnetic field strength, isotropy is maintained except in the case of a Gamma 8 ground state. Isotropy and C-type term saturation characteristics are illustrated by calculations of the MCD associated with the 4A2g(t3) to 4T2g(t2e), 4A2g(t3) to 2T1g(t3) and 4A2g(t3) to 2Eg(t3) transitions of a d3 ion at a site of Oh symmetry.Keywords
