Abstract
A theoretical study of the site-diluted spin 3/2 transverse Ising mode l is presented using an effective field method within the framework of a single-site cluster theory. The effective field equations are deriv ed using a probability distribution method based on the use of general ized Van der Waerden identities, that account exactly for the single-s ite kinematic relations. Correlations between the site disorder and th e local configurational-dependent thermal averages of the spin variabl es are included. The critical temperature at which the longitudinal ma gnetization Vanishes is studied both as a function of dilution and as a function of the transverse field strength. The thermal dependence of the longitudinal and transverse magnetizations, and higher-order magn etization moments, are also studied.
