Competing ferromagnetic and antiferromagnetic phases on the frustrated Ising honeycomb lattice

Pietro F. Dias, Fabio M. Zimmer, Nikolaos G. Fytas +1

We investigate the frustrated $J_{1}$ - $J_{2}$ - $J_{3}$ Ising model on the honeycomb lattice, featuring first- and second-neighbor ferromagnetic couplings ( $J_{1} > 0$ and $J_{2} > 0$ ) and third-n…

The correlated cluster mean-field approach to the frustrated Ising model on the honeycomb lattice

Carlos H. D. Batista, M. Schmidt, F. M. Zimmer

We study the $J_{1}$ - $J_{2}$ Ising model on the honeycomb lattice, considering ferromagnetic interactions between first neighbors ( $J_{1}$ ) and antiferromagnetic interactions between sec…
