Abstract

Phase transitions of the spin-1 (Formula presented) chain with a single-ion anisotropy in a staggered magnetic field are studied. We obtain interesting phase diagrams consisting of ferromagnetic, partially ferromagnetic, (Formula presented) antiferromagnetic (AF) and large-(Formula presented) phases. By using the twist-boundary-condition method, a Gaussian critical line is found between the AF phase and the large-(Formula presented) phase. A multicritical point lies among the (Formula presented) AF and large-(Formula presented) phases. An Ashkin-Teller type of bifurcation does not appear.
