Abstract :
The effect of random crystal-field on the magnetic properties of the semi-infinite system is investigated by the use of the mean field approximation. In this system, the sites of the surface and bulk are occupied by spin- 1/2 and spin-1, respectively. The appearance of the partly ferromagnetic phase, in bulk, gives rise to different types of topology of phase diagrams. The system exhibits tricritical and multicritical points.
