Aim of this paper to investigate Soret (thermal-diffusion) and Dufour (diffusion-thermo) effects on unsteady MHD flow through porous medium in the presence of a magnetic field with hall current. The similarity solutions were obtained using suitable transformations and the resulting similarity ordinary differential equations were solved by finite difference method. The influences of different flow parameters on velocity, temperature and concentration fields are investigated. The skin frictions at the plate due to tangential and lateral velocity fields are obtained in non-dimensional form. The effects of the physical parameters like Dufour number (Du) and Soret number (Sr) on these fields are discussed through graphs and results are physically interpreted.
