Abstract

Only recently has it become clear that quantum fluctuations do not destroy long-range oreder in the ground state of the 2D S = 1 2 square-lattice Heisenberg antiferromagnet. We reporta neutron scattering study of the static structure factor of Su2CuO2Cl2, which is an optimal experimental realization of this model. Excellent agreement for the magnetic correlation length is found to exist between theory. Monte Carlo results and our experiment.
