Many-body Green's function theory of Heisenberg films
P. Fröbrich, P. J. Kuntz
The treatment of Heisenberg films with many-body Green's function theory (GFT) is reviewed. The basic equations of GFT are derived in sufficient detail so that the rest of the pape…

The magnetic reorientation transition in thin ferromagnetic films treated by many-body Green's function theory
P. Fröbrich, P. J. Kuntz
This contribution describes the reorientation of the magnetization of thin ferromagnetic Heisenberg films as function of the temperature and/or an external field. Working in a rota…
