Light Scattering from High-Lying Electronic Excitations in CoF2

Abstract
Raman spectra of CoF2 above and below its Néel point have been obtained which show four very weak lines in the region between 700 and 1500 cm−1. These are attributed to transitions from the ground state to the four highest‐lying levels within the resolved 4Γ4+ manifold of Co2+. The spectra are in good agreement with data for Co2+ in MgF2.
