“…The basic theoretical problem is the examination of the magnetic excitation and the phase transitions in these systems. Of these, magnetic films are very important from both the theoretical and the experimental standpoint [5][6], and can be studied as models of the magnetic size effect [7] and as quasi-two dimensional systems. The magnetic and phase transition properties of semi-infinite Ising systems have been investigated for many years [8][9][10][11].…”

Within the framework of the effective field theory, we examine the phase diagrams of a spin-1/2 Ising film, with a spin-3/2 atoms on the top and bottom surfaces, and the corresponding semiinfinite system. In particular, the effects of surface single-ion anisotropy on the phase diagram and critical value for surface ordering are clarified. The system shows the existence of a critical value of the ratio of the surface interaction to the bulk one above which the surface magnetism appears. This critical value moves to lower values when D s increases. The critical surface temperature exhibits a characteristic behavior namely when large negative D s are selected.

Within the framework of the effective field theory, we examine the phase transitions in a spin-1/2 Ising model of an alternating magnetic superlattice. We calculate the critical temperature of the alternating superlattice as a function of the intralayer and interlayer exchange interactions and the film thickness. The effects of modified surface layers on the critical temperature are also considered.

“…It is, among other things, the theory of disordered diluted alloys [3,14,15], random field problems [15,16], amorphization [14,17,18] and surface magnetism [4,19]. In the equivalent, integral operator version, the method has been applied to studies of thin magnetic films [20,21]. At the same time, great efforts were put into application of H-K method to higher spins problem [22,23].…”
