【 摘 要 】

The Ising model with the nearest-neighbor interaction J 2 and four-spin interaction J 4 on the honeycomb-lattice is investigated. The correlation relationships among two-spins and four-spins are calculated. The effects of spin-spin interactions on phase diagrams are investigated analytically and numerically. Evidence from our derivation indicates that the classification of the phase-transition depends on the ratio of J 4 to J 2.
