Query: Magnetic Properties of High Temperature Superconductors: a Spin Liquid
  Approach. Talk given at Stanford Spectroscopy Meeting, 1995.   We argue that strongly correlated two dimensional electrons form a spin
liquid in some regimes of density and temperature and give the theory of the
magnetic properties of this spin liquid using the representation in terms of
femions interacting with a gauge field. This state is characterized by
anomalous power law spin correlations and discuss the implications of these
correlations for the temperature dependence of NMR relaxation rates $1/T_1$ and
$1/T_2$ and for the uniform susceptibility. We also discuss the transition from
the spin liquid to antiferromagnet and the critical behavior of these
properties at the transition. We compare these theoretical results with the
data on high $T_c$ superconductors. Finally, we discuss the formation of the
spin gap due to the spin exhange interaction between adjacent layers in
bilayered materials.
