1 Dec 1999 | | Journal: | Australian J. Phys. 53(2000)453-459 | | Subject: | Materials Science; Disordered Systems and Neural Networks | cond-mat.mtrl-sci cond-mat.dis-nn | | Abstract: | We consider a finite ferroelectric superlattice in which the elementary unit cell is made up of l atomic layers of type A and n atomic layers of type B. Based on the transverse Ising model we examine the phase transition properties of the ferroelectric superlattice. Using the transfer matrix method we derive the equation for the Curie temperature of the superlattice. Numerical results are given for the dependence of the Curie temperature on the thickness and exchange constants of the superlattice. | | Source: | arXiv, cond-mat/9912012 | | Services: | Forum | Review | PDF | Favorites | |
