Abstract
The S = 1/2 ferromagnetic XY model on the triangular lattice is investigated by quantum Monte Carlo methods based on the Suzuki-Trotter formula. The squared magnetization (M2x) / N2 is calculated for finite temperatures and extrapolated to T = 0. The existence of the long-range order is discussed. Kubo's susceptibility χxx is also calculated and compared with the squared magnetization.
