摘要
The critical behavior of a ferromagnetic spin-1 Ising superlattice in a transverse field is studied using the effective field theory with a probability distribution technique that accounts for the self-spin correlation functions. The critical temperature of the system is calculated as a function of the exchange interactions in each material, the strength of the transverse field and the thickness of the constituents in a unit cell. A critical value of the interface exchange interaction above which the interface magnetism appears is found. (C) 2001 Elsevier Science B.V. All rights reserved.
