  The results of extensive Monte Carlo simulations of classical spins on the
two-dimensional kagome lattice with only dipolar interactions are presented. In
addition to revealing the six-fold degenerate ground state, the nature of the
finite-temperature phase transition to long-range magnetic order is discussed.
Low temperature states consisting of mixtures of degenerate ground state
configurations separated by domain walls can be explained as a result of
competing exchange-like and shape anisotropy-like terms in the dipolar
coupling. Fluctuations between pairs of degenerate spin configurations are
found to persist well into the ordered state as the temperature is lowered
until locking in to a low-energy state.
