| Abstract: | We have used the Monte Carlo simulation to study the phase diagrams and the magnetic properties of a single nano-graphene layer with next-nearest neighbors coupling and four-spin interaction . Interesting behaviors have been found. In particular, the nanographene can present tricritical and triple points for appropriate system parameters. |
