Abstract
We present ESR data on the spin glass Ag Mn, analysed for T > T g in a completely new way: 1) The linewidth W as a function of H res( T)/ M( H res, T) yields a universal curve for all data: no explicit frequency dependence of the linewidth can be observed. 2) For T g ≤ T ≤ 1.6 T g the excess width W ex shows for all data a power law as a function of the order parameter susceptibility (χ 1) W ex = χ p q.
