Dynamics of magnetic nano particles in a viscous fluid driven by rotating magnetic fields
Klaus D. Usadel
The rotational dynamics of magnetic nano particles in rotating magnetic fields in the presence of thermal noise is studied both theoretically and by performing numerical calculatio…
Dynamics of magnetic single domain particles embedded in a viscous liquid
Klaus D. Usadel, Clemens Usadel
Kinetic equations for magnetic nano particles dispersed in a viscous liquid are developed and analyzed numerically. Depending on the amplitude of an applied oscillatory magnetic fi…
Exchange enhanced anisotropy in ferromagnetic/antiferromagnetic multilayers: dynamic consequences
R. L. Stamps, K. Usadel
The phenomena of exchange anisotropy is well known in terms of static magnetization properties such as enhanced coercivity and magnetization loop shifts. These effects are primaril…
Origin of asymmetric reversal modes in ferromagnetic/antiferromagnetic multilayers
B. Beckmann, U. Nowak, K. D. Usadel
Experimentally an asymmetry of the reversal modes has been found in certain exchange bias systems. From a numerical investigation of the domain state model evidence is gained that…
Domain wall mobility in nanowires: transverse versus vortex walls
R. Wieser, U. Nowak, K. D. Usadel
The motion of domain walls in ferromagnetic, cylindrical nanowires is investigated numerically by solving the Landau-Lifshitz-Gilbert equation for a classical spin model in which e…
Interface Motion in Disordered Ferromagnets
L. Roters, S. Lubeck, K. D. Usadel
We consider numerically the depinning transition in the random-field Ising model. Our analysis reveals that the three and four dimensional model displays a simple scaling behavior…
