Abstract
Using an expansion technique for cluster identities of spin-1 localise d spin systems, we have investigated the phase diagram of a transverse spin-1 Ising ferromagnet with random longitudinal magnetic field. The longitudinal and transverse magnetizations, the quadrupolar moments a nd the phase diagrams are calculated using a bimodal distribution of t he longitudinal magnetic field. General formula, applicable to structu res with arbitrary coordination number N, are given.
