摘要：

We present the first realistic mode-coupling calculation of the high-temperature EPR linewidth of a two-dimensional antiferromagnet. The theory is valid for temperatures where the linewidth is determined by diffusion-controlled dynamics. The angular and temperature dependence of the linewidth are in good agreement with experiment, although the absolute values are somewhat too small ({reversed tilde}40%). © 1979.
