| Abstract: | A high density perturbation method is employed to calculate the two-magnon Raman scattering spectra of antiferromagnets at finite temperatures. The theory incorporates the leading order effects of magnon-magnon interactions, and the results are applied to RbMnF3 and NiO in the antiferromagnetic phase. A comparison is made with experimental work and fairly good agreement is obtained. |
