Abstract: The entropy at T = 0 of the spin-glass state of the random-bond binary mixture of the ferro- and antiferromagnetic exchange energies (±J model) is calculated by the method of the pair approximation. The values of S(T = 0) per spin are 0.0215607, 0.0981090, and 0.0390764, for z = 3, the SG1 state of z = 4, and the SG2 state of z = 4, respectively.
