| Abstract: | The Ising S=1 systems are transferred to a Fermion system in which the total number of particles is not a constant by the quantum many-body method in the reference[1]. we obtained rigorously the ground state energy of the antiferromagnetics of Ising S=1 hexagonal-close-packed lattice with nearest neighbors and next nearest neighbors interaction in an arbitrary magnetic field, and also the phase equilibrium diagram at T=OK. |
