摘要: A spin-1 Ising model with random bonds and crystal-field interactions Delta i is investigated by the use of effective-field theory correlations. The general expressions for evaluating second-order phase transition tricritical point are obtained. For a particular case p( i)=p delta ( i- )+p i) behaviour p studied honeycomb lattice.
