摘要：
We study the NMR response of a highly polarized, exchange-coupled classical spin system with two isotopes of nearly equal gyromagnetic ratios. We integrate numerically the Heisenberg equations of motion and determine the dynamic susceptibility by using the fluctuation-dissipation theorem. Resulting lineshapes are compared with predictions of the mean-field theory.
