The three‐dimensional spin‐1 Ising model with crystal field interactions exhibits tricritical behaviour. Using an expansion technique for cluster identities of spin‐1 localized spin systems, the influence of transverse magnetic field on this behaviour is studied. Temperature‐crystal field phase diagrams are investigated for different values of transverse field. The longitudinal and transverse magnetizations, as well as the quadrupolar moments are calculated. General formulas applicable to structures with arbitrary coordination number N , are given.
