Abstract |
We present Monte Carlo simulations in a generalized uniformly frustrated triangular-lattice model of XY spins. The frustration is varied by changing the relative strength, $\etha$, of one of the bonds of the unit well. We found that the ground state transforms from ferromagnetic to anti-ferromagnetic along the variable bond direction for a critical value of $\etha=-1/\sqrt(3)$. Simultaneously, the phase transition towards the paramagnetic state at high temperatures changes from purely Kosterlitz-Thouless like to one of mixed character |
