| Abstract: | The boundary between the spin-glass state and the ferromagnetic state (pF-G) of the bond-random (±J) Ising model in the face-centred cubic lattice at T = 0 is calculated by the method of tetrahedron approximation in the simple version. The obtained value is, pF-G = 0.682, which is a little larger than the triple point pt = 0.654, and the model shows the reentrant behavior. |
