| Abstract: | The phase diagrams and magnetizations of two nanoscaled thin films with a negative interlayer interaction at the surfaces, described by the transverse Ising model, are investigated by the use of the effective field theory with correlations. It is proved that two compensation points induced by the surface parameters (exchange interaction and transverse field at the surfaces) can be found in these nanosystems. |
