Raman light scattering from excitons and magnons in cobalt fluoride

Abstract

We have observed one-particle, inelastic, polarized light scattering from low-lying excitons and magnons in single-crystal cobalt fluoride (CoF2) at 2°K. Because of the orbital nature of these excitations, the cross sections (10-33-10-32 cm2/sr) are much larger than for one-magnon scattering in the other case, which has been measured (FeF2, 10-35 cm2/sr). Our measured cross sections are in good agreement with a recent calculation by Ishikawa and Moriya. © 1970 The American Physical Society.
