Characteristic phenomena in nanoscaled transverse Ising thin films with diluted surfaces

Abstract

The phase diagrams and magnetizations of two nanoscaled thin films with a negative interlayer interaction and dilution at the surfaces, described by the transverse Ising model, are investigated by the use of the effective field theory with correlations. A lot of characteristic phenomena which heavily depend on the surface parameters can be found in them. In particular, the behaviors of a compensation point (or points) in these nanosystems with a negative interlayer interaction at the surfaces are examined by changing the transverse field and the physical parameters at the surfaces.
