Transverse ordering of an antiferromagnet in a field with oblique angle to the easy axis
M. Acharyya, U. Nowak, K. D. Usadel
Motivated by the recent experimental observations [Phys Rev B 57 R11051 (1998)] of transverse spin ordering in FeBr_2 induced by a magnetic field with oblique angle to the easy axi…

Dynamics of Domains in Diluted Antiferromagnets
U. Nowak, J. Esser, K. D. Usadel
We investigate the dynamics of two-dimensional site-diluted Ising antiferromagnets. In an external magnetic field these highly disordered magnetic systems have a domain structure w…

Monte Carlo Simulation of Ising Models with Dipole Interaction
U. Nowak, A. Hucht
Recently, a new memory effect was found in the metamagnetic domain structure of the diluted Ising antiferromagnet by domain imaging with Faraday contrast. Esse…
