摘要：
The phase transitions of a ferromagnet spin-1/2 Ising superlattice consisting of two different materials are examined using the effective field theory. The critical temperature of the system is studied as a function of the thickness of the constituents in a unit cell. exchange interactions in each material and transverse field. A critical value of the interface exchange interaction above which the interface magnetism appears is found. (C) 1999 Elsevier Science B.V. All rights reserved.
