A spin‐1 Ising model with the presence of transverse and crystal fields (CTIM) is studied within the scheme of the finite cluster approximation (FCA). The phase diagrams and the other critical behaviour are numerically investigated for the honeycomb lattice. FCA yields results which are superior to those of the standard mean‐field approximation (MFA).
