We investigate a magnetic transition in the half-filled Hubbard model on the triangular lattice. By making use of the path-integral renormalization group (PIRG) method with a spin-rotated frame, we calculate the ground state energy and charge/spin correlation functions for a cluster with 36 sites. W
