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...

The effects of random crystal field on the stationary states of the kinetic spin-1 Blume Capel model are studied using the Glauber-type stochastic dynamics under the time-dependent oscillating field assumption. Our investigation, based on the equilibrium ground state phase diagram, revealed many...
