Abstract
The three-dimensional spin-1 Ising model with crystal field interactio ns exhibits tricritical behaviour. Using an expansion technique for cl uster identities of spin-1 localized spin systems, the influence of tr ansverse magnetic field on this behaviour is studied. Temperature-crys tal field phase diagrams are investigated for different values of tran sverse 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.
