abstract = {<p style="text-align: justify;">The low temperature properties of double exchange model in triangular
lattice are investigated via truncated polynomial expansion method (TPEM), which
reduces the computational complexity and enables parallel computation. We found
that for the half-filling case a stable 120<sup>◦</sup>spin configuration phase occurs owing to the
frustration of triangular lattice and is further stabilized by antiferromagnetic (AF) superexchange
interaction, while a transition between a stable ferromagnetic (FM) phase
and a unique flux phase with small finite-size effect is induced by AF superexchange
interaction for the quarter-filling case.</p>},
