Abstract
In this paper,a renormalization group scheme within the framework of the mean field theory is used to investigate the critical behavior at the surface of a semi infinite Ising system with mixed spins,i.e.S=1 at the surface and σ=1/2 in the bulk.The effects of a random field on the surface phase diagrams are obtained.
