摘要：

In both cases of ferromagnetic and antiferromagnetic nearest-neighbour intrachain interactions, the ground state phase diagrams are obtained exactly for the spin S = 1 axial next-nearest-neighbour Ising (ANNNI) model with the single-ion anisotropy, - DSi2, by using the fundamental spin arrangement (FSA) method. The ground state phase diagrams include partially non-magnetized spin state, which we expect to be relevant to the realization of the partially disordered phases found in real substances at finite temperature.
