Vl. Kovarskii et Av. Khristov, LIMITING PASSAGE IN A PSEUDO-SPIN MODEL O F STRUCTURAL DISORDERING WITH BARRIERS, Fizika nizkih temperatur, 22(3), 1996, pp. 293-295
The Ising model is considered which takes into account the energy barr
ier U-0 between states. The limit U-0 --> infinity is shown to lead to
ordinary Ising model. The conditions are found when this model is the
equivalent to the ternary Potts model with effective value of relativ
e multiplicity of states degeneration. The field of the model applicab
ility has been defined.
