Explosive Ising
Sebastian Angst, Silvio R. Dahmen, Haye Hinrichsen +2
We study a two-dimensional kinetic Ising model with Swendsen-Wang dynamics, replacing the usual percolation on top of Ising clusters by explosive percolation. The model exhibits a…
Mean-field scaling function of the universality class of absorbing phase transitions with a conserved field
S. Lubeck, A. Hucht
We consider two mean-field like models which belong to the universality class of absorbing phase transitions with a conserved field. In both cases we derive analytically the order…
Nonanalytic correlation length in Ising systems with one surface defect line
A. Hucht
A two-dimensional Ising system with ferromagnetic coupling and one defect line at distance L from the surface is solved exactly using Pfaffians. The system shows a singularity in t…
Influence of magnetic fields on the spin reorientation transition in ultra-thin films
A. Hucht, K. D. Usadel
The dependence of the spin reorientation transition in ultra-thin ferromagnetic films on external magnetic fields is studied. For different orientations of the applied field with r…
On the reorientation transition of ultra-thin Ni/Cu(001) films
A. Hucht, K. D. Usadel
The reorientation transition of the magnetization of ferromagnetic films is studied on a microscopic basis within a Heisenberg spin model. Using a modified mean field formulation i…
Reorientation of Spin Density Waves in Cr(001) Films induced by Fe(001) Cap Layers
P. Bödeker, A. Hucht, A. Schreyer +3
Proximity effects of 20 Åthin Fe layers on the spin density waves (SDWs) in epitaxial Cr(001) films are revealed by neutron scattering. Unlike in bulk Cr we observe a SDW with its…
