MAGNETIC-PROPERTIES AND INTERFACE DELOCALIZATION IN THE 3-DIMENSIONALISING-MODEL WITH DEFECT-PLANE AMORPHIZATION

Magnetic properties and interface delocalization of the spin-1/2 Ising model on a cubic lattice with an amorphized defect plane that divides the system into two semi-infinite ones are investigated by the use of the effective-field theory. The global phase diagrams, which represen t the connection between amorphized defect-plane order and wetting tra nsitions (from partial to complete wetting), are given in the case of two equivalent semi-infinite systems (the same coupling) and in the ca se of different semi-infinite systems. The influence of the amorphizat ion in these global phase diagrams is also studied. Moreover, magnetic properties which illustrate some interesting behavior for the amorphi zed systems are investigated.
