Elementary transitions and magnetic correlations in two-dimensional disordered nanoparticle ensembles
G. M. Pastor, P. J. Jensen
The magnetic relaxation processes in disordered two-dimensional ensembles of dipole-coupled magnetic nanoparticles are theoretically investigated by performing numerical simulation…
Two-dimensional Heisenberg antiferromagnet in a transverse field
P. J. Jensen, K. H. Bennemann, D. K. Morr +1
We investigate the magnetic reorientation in a two-dimensional anisotropic antiferromagnet due to a transverse magnetic field. Using a many-body Green's function approach, we show…
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…
Magnetic reordering in the vicinity of a ferromagnetic/antiferromagnetic interface
P. J. Jensen, H. Dreysee, Miguel Kiwi
The magnetic arrangement in the vicinity of the interface between a ferromagnet and an antiferromagnet is investigated, in particular its dependence on the exchange couplings and t…
Comment on "Magnetic phase transition in Co/Cu/Ni/Cu(100) and Co/Fe/Ni/Cu(100)"
P. J. Jensen, C. Sorg, A. Scherz +3
In a recent Letter the phase diagram of Co/Cu/Ni/Cu(100) and Co/Fe/Ni/Cu(100) trilayers was determined experimentally as well as theoretically. Whereas we do not object the present…
Many-body Green's function theory of ferromagnetic Heisenberg systems with single-ion anisotropies in more than one direction
Huai-Yu Wang, Zhen-Hong Dai, P. Fröbrich +2
The behaviour of ferromagnetic systems with single-ion anisotropies in more than one direction is investigated with many-body Green's function theory generalizing earlier work with…
