  Within the framework of the QED3 theory of cuprates it is argued that bulk
antiferromagnetic (AF) order can coexist with d-wave superconductivity in the
underdoped region, in agreement with recent experiments. The AF order arises
from the phase fluctuating d-wave superconductor via the mechanism of
spontaneous chiral symmetry breaking, provided that fluctuations are
sufficiently strong. The phase diagram for this coexistence is mapped out by
means of analytical and numerical solutions of the underlying Dyson-Schwinger
equation in the large N limit.
