Coupled ferro-antiferromagnetic Heisenberg bilayers investigated by many-body Green's function theory
P. Fröbrich, P. J. Kuntz, P. J. Jensen
A theory of coupled ferro- and antiferromagnetic Heisenberg layers is developed within the framework of many-body Green's function theory (GFT) that allows non-collinear magnetic a…
The treatment of zero eigenvalues of the matrix governing the equations of motion in many-body Green's function theory
P. Fröbrich, P. J. Kuntz
The spectral theorem of many-body Green's function theory relates thermodynamic correlations to Green's functions. More often than not, the matrix governing the equations of motion…
Anisotropic susceptibilities of thin ferromagnetic films within many-body Green's function theory
P. Fröbrich, P. J. Kuntz
Transverse and parallel static susceptibilities of in-plane uniaxial anisotropic ferromagnetic films are calculated within many-body Green's function theory on the basis of an Heis…
Many-body Green's function theory for thin ferromagnetic anisotropic Heisenberg films: treatment of the exchange anisotropy
P. Fröbrich, P. J. Kuntz
The many-body Green's function theory developed in our previous work for treating the reorientation of the magnetization of thin ferromagnetic films is extended to include the exch…
