摘要：

We study the antiferromagnetic (AF) spin-1 Blume-Capel (BC) model on a recursive lattice called twofold Cayley tree. Both sublattice magnetizations of the Ising spins are exactly calculated with the aim to obtain phase diagrams and thermal variations of the sublattice magnetizations. The finite-temperature phase diagrams exhibit a small reentrant region if the twofold Cayley tree with a sufficiently high coordination number q > 5 is considered. The results are also compared to obtained by Bethe lattice consideration in recursive approach.
