Single-ion versus exchange anisotropy in calculating anisotropic susceptibilities of thin ferromagnetic Heisenberg films within many-body Green's function theory
P. Fröbrich, P. J. Kuntz
We compare transverse and parallel static susceptibilities of in-plane uniaxial anisotropic ferromagnetic Heisenberg films calculated in the framework of many-body Green's function…
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…
The spectral theorem of many-body Green's function theory when there are zero eigenvalues of the matrix governing the equations of motion
P. Fröbrich, P. J. Kuntz
In using the spectral theorem of many-body Green's function theory in order to relate correlations to commutator Green's functions, it is necessary in the standard procedure to con…
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…
