摘要：
In this article, we show by Monte Carlo simulations that the phase transition is definitely of first order in the antiferromagnetic stacked triangular lattices with both classical XY and Heisenberg spins in a range of the antiferromagnetic next-nearest neighbor interaction J2. The phase diagram in the (J2/J1, T) space (J1: nearest-neighbor interaction, T: temperature) is shown and discussed.
