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…
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…
Quantum Fluctuations and the Exchange Bias Field
G. J. Mata, E. Pestana, M. Kiwi +1
Ground-state fluctuations reduce the zero-temperature magnetic moments of the spins in a quantum antiferromagnet. In the neighborhood of surfaces, interfaces, and other defects whi…
In-plane magnetic reorientation in coupled ferro- and antiferromagnetic thin films
P. J. Jensen, H. Dreysse
By studying coupled ferro- (FM) and antiferromagnetic (AFM) thin film systems, we obtain an in-plane magnetic reorientation as a function of temperature and FM film thickness. The…
