The spin dynamics in the helical chain Co(hfac)2NITPhOMe has been investigated by 1H NMR and μSR relaxation. In the temperature range 15<T<60 K, the results are consistent with the relaxation of the homogeneous magnetization. For T≤15 K, NMR and μSR evidence a second spin relaxation mechanism, undetected by the magnetization measurements. From the analysis of these data, insights on this novel relaxation process are derived.
