- 論文の詳細を見る
The Ising model on the triangular lattice with antiferromagnetic nearest-neighborand ferromagnetic second neighbor interactions is treated using the cluster variationmethod with a hexagon of seven spins as the basic cluster. The para, the partialdisordered (PD), the two sublattice ferri and the three-sublattice ferri phases and theirboundaries are derived. The results are examined varying temperature, magnetizationand the magnetic field, and are compared with the previous work by Kaburagi,Tonegawa and Kanamori. The trend is noticed that the PD phase shrinks as the ap-proximation is improved.
