摘要：
A two-fold Cayley tree with fully q-coordinated sites is constructed and the spin-1 Blume-Capel model inthe presence of an external magnetic field is solved exactly.The relevant properties such as magnetization m and squaremagnetic moment q are investigated as functions of temperature and external magnetic field both for ferromagneticand antiferromagnetic couplings.In the study,we propose a possible mechanism of the plateau based on the exchangecouplings.
