Abstract
Six new phase diagrams, including a novel multicritical topology and two new ordered phases, are obtained by the global mean‐field theory of the spin‐1 Ising model with only nearest‐neighbor interactions, for negative biquadratic couplings. Renormalization‐group studies indicate a threshold spatial dimension, above and below which different sequences of phase diagrams occur.This publication has 16 references indexed in Scilit:
