Nuclear transverse relaxation rates of the Cu" and the ligand nuclei F" and Cl" inK.CuF. and (CH.,NH.).CuCl. have been studied by the pulsed NMR method in themagnetically ordered state. In a small external magnetic field thcc steep decrease of therelaxation rate caused by the small anisotropy field within layer as well as the two-dimensionality of these compounds has been observed. The relaxation rates due to thescattering of the electronic spin-wave (Raman process) and the invdirect coupling (Suhl-Nakamura interaction) are calculated for the present nearly two-dimensional fer-romagnets including the interlayer exchange interaction and the X Y like anisotropy inthe intralayer exchange one. It turns out that the X Y like anisotropy considerablydecreases the relaxation rate. l'he theoretical calculation agrees well with the observatton.
