Abstract
An effective-field theory of mixed spin—1/2 and spin-1 Ising system with random bond and crystal-field interactions is developed. The general expressions for evaluating the thermodynamic quantities are obtained. In the last section, transition temperature and tricritical behavior are examined for the mixed ferromagnetic spin system withz=3, wherez is the coordination number. The obtained results are reasonable in comparison with exact and approximate ones. Owing to the simplicity, the present method can be applied to a wide class of the random systems.
