Abstract
The temperature dependence of the ESR spectra of Mn2+ ions has been studied in the incommensurate phase of [N(CH3)4]2ZnCl4 crystal. The edge-singularity of the ESR spectra was analyzed in terms of an incommensurate spatial modulation of the fine structure tensor. The plane wave modulation model is a good approximation in the wide temperature range between T I and T c. The critical index β for the amplitude of modulation is 0.46±0.05 in this temperature range.Keywords
