Magnetic properties of the site-diluted spin-1 Ising superlattice - art. no. 054436

The critical behavior of a diluted spin-1 Ising superlattice is examined us ing the effective-field theory with a probability distribution technique th at accounts for the self-spin correlation functions. The critical temperatu re of the system is studied as a function of the exchange interactions in e ach material, the concentration of magnetic atoms, and the thickness of the constituents in a unit cell. A critical value of the interface exchange in teraction above which the interface magnetism appears is found. We calculat ed also some magnetic properties of a diluted spin-1 Ising superlattice suc h as the layer longitudinal magnetizations and quadrupolar moments. It is s hown that the properties of the diluted system are different from those of the corresponding pure system.
