Abstract

Two-magnon absorption and Raman experiments create pairs of magnons in close proximity, and hence, the magnon-magnon interaction has an important effect on the spectral line shape. Green's-function methods have been used to calculate this effect and the results applied the example of cubic antiferromagnets like RbMnF3. Similar techniques are used to find the effect of exciton-magnon interaction on the sidebands in RbMnF3; corresponding experimental results are presented.
