Abstract
The phase transitions of a ferromagnet spin-1/2 Ising superlattice consisti ng of two different materials are examined using the effective field theory . The critical temperature of the system is studied as a function of the th ickness of the constituents in a unit cell. exchange interactions in each m aterial and transverse field. A critical value of the interface exchange in teraction above which the interface magnetism appears is found. (C) 1999 El sevier Science B.V. All rights reserved.
