Abstract. This paper deals with two-fluid Bianchi type-VI0 anisotropic cosmological model coupled with zero mass scalar field in Einstein's theory of gravitation. To get a determinate model, it is assumed that the scalar expansion (θ) of the model is proportional to the shear (σ). Exact solution of the field equations for interacting matter and radiation field is presented which represents an expanding cosmological model of the universe. This paper also discusses in detail the behaviour of associated fluid parameters and kinematical parameters. Some physical properties of the model are discussed.
