Abstract
Ordering process of the antiferromagnetic Heisenberg model on the square is investigated mainly by a quantum Monte Carlo method. The effect of quantum fluctuation is studied by investigating the existence of long range order, the response function and the spin configurations. The magnetic susceptibility is also reported.
