Simulation of Magnetization Switching in Nanoparticle Systems
D. Hinzke, U. Nowak
Magnetization reversal in magnetic nanostructures is investigated numerically over time-scales ranging from fast switching processes on a picosecond scale to thermally activated re…
Brownian dynamics approach to interacting magnetic moments
O. Chubykalo, R. Smirnov-Rueda, M. A. Wongsam +3
The question how to introduce thermal fluctuations in the equation of motion of a magnetic system is addressed. Using the approach of the fluctuation-dissipation theorem we calcula…
Magnetization Switching in Nanowires: Monte Carlo Study with Fast Fourier Transformation for Dipolar Fields
D. Hinzke, U. Nowak
For the investigations of thermally activated magnetization reversal in systems of classical magnetic moments numerical methods are desirable. We present numerical studies which ba…
Uniform susceptibility of classical antiferromagnets in one and two dimensions in a magnetic field
D. Hinzke, U. Nowak, D. A. Garanin
We simulated the field-dependent magnetization m(H,T) and the uniform susceptibility χ(H,T) of classical Heisenberg antiferromagnets in the chain and square-lattice geometry using…
Magnetization Switching in Small Ferromagnetic Particles: Nucleation and Coherent Rotation
U. Nowak, D. Hinzke
The mechanisms of thermally activated magnetization switching in small ferromagnetic particles driven by an external magnetic field are investigated. For low uniaxial anisotropy th…
Magnetization switching in a Heisenberg model for small ferromagnetic particles
D. Hinzke, U. Nowak
We investigate the thermally activated magnetization switching of small ferromagnetic particles driven by an external magnetic field. For low uniaxial anisotropy the spins can be e…
