We report quantitative neutron scattering measurements of the evolution with doping of the Neel temperature, the antiferromagnetic correlations, and the ordered moment of as-grown, nonsuperconducting Nd2-xCexCuO4+/-delta (0less than or equal toxless than or equal to0.18). The instantaneous correlation length can be effectively described by our quantum Monte Carlo calculations for the randomly site-diluted nearest-neighbor spin-1/2 square-lattice Heisenberg antiferromagnet. However, quantum fluctuations have a stronger effect on the ordered moment, which decreases more rapidly than for the quenched-disorder model.
