In this paper, we have investigated Ruban’s cosmological model in Seaz-Ballester theory of gravitation under the influence of perfect fluid, cloud string and thick domain wall coupled with electromagnetic field. The general solution of Einstein’s field equations for perfect fluid, cloud string of cosmological model in Seaz-Ballester theory of gravitation are obtained with the help of relation between metric coefficients and equation of state except Domain Wall, Also discussed some physical and kinematical properties of the models. The main aim of the paper is to compare the obtained results of perfect fluid, cloud string and thick domain wall within the framework of Saez-Ballester theory.
