Abstract
We study the competition between nonmagnetic (dimer or flux) states and sho rt-range antiferromagnetically ordered RVB states in the t-J model and pres ent a finite temperature phase diagram. We show that for a wide range of te mperatures and dopings, the stable phase results to be a state in which bot h the flux and the RVB parameters are nonzero. (C) 2000 Elsevier Science B. V.
