Abstract
The temperature and doping dependence of the dynamic spin susceptibili ty in the planar t-J model is studied in small systems. Finite tempera ture dynamic correlation functions are calculated on clusters with up to 20 sites with the method, based on the Lanczos diagonalization tech nique and random sampling. The 1/T-1 NMR relaxation rate is estimated from the low frequency Limit of dynamic spin correlation functions.
