We numerically simulate the critical behavior of up to 1502 classical Heisenberg spins in a two-dimensional square lattice with nearest-neighbor coupling and periodic boundary conditions. The simulation of this model exhibits a ferromagnetic phase transition to a state with lattice-spanning order at T c ~ 0.6. The phase transition has unusual features reminiscent of a Kosterlitz-Thouless (topological) phase transition; it is suggested that topological defects may play an important role in the ordering of this system.
