Within the Mori approach the magnetic longitudinal relaxation function in the singlet—triplet model near the Curie temperature is analysed. The influence of mode—mode coupling effects, especially of those of transverse intratriplet excitations, on the long‐time tail of relaxation function and on the line shape of the central mode is also discussed.
