Abstract
Strongly correlated two-dimensional electrons are believed to form a spin liquid in some regimes of density and temperature. As the density is varied, one expects a transition from this spin-liquid state to a spin-density-wave antiferromagnetic state. In this paper we show that it is self-consistent to assume that this transition is second order and, on this assumption, determine the critical behavior of the 2 susceptibility, the NMR rates and and the uniform susceptibility. We compare our results to data on high- materials.
