  Title Phase transitions in triangular arrays of XY spins with variable coupling Type Journal Article
  Year 1996 Publication Czechoslovak Journal of Physics Abbreviated Journal  
  Volume 46 Issue S4 Pages 1905  
  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
