Abstract:
The ground states of the triangular Ising system with the first, second and third nearest neighbor interactions, whose interaction constants are denoted by J1, J2 and J3, in the absence of an external magnetic field are obtained by the analytical way. It is shown that in the coordinate space of (J1, J2, J3), a total of seven ground states are found and many states are degenerated on the boundary planes between domains of those ground states. Spin configurations of the ground states are shown and the phase diagram of the ground states is given.
