摘要:Critical conditions for the first-order phase transition are determined for a system of 1/2 spins on the Ising model with a four-spin coupling term. The critical point parameters [Left Angle Bracket] Sz [Right Angle Bracket] c, Tc and Ec are found from the mean field theory. Relations between the three critical values and the four-spin coupling strength are discussed.
