Phase Diagram of Magnetization Reversal Processes in Nanorings
Wen Zhang, Stephan Haas
We investigate magnetization reversal processes of magnetic nanorings. Using a recently developed efficient cartesian coordinates fast multipole method, magnetization switching pha…
Fractal dimension and threshold properties in a spatially correlated percolation model
Hongting Yang, Wen Zhang, Noah Bray-Ali +1
We consider the effects of spatial correlations in a two-dimensional site percolation model. By generalizing the Newman-Ziff Monte Carlo algorithm to include spatial correlations,…
Switching Mechanism in Ferromagnetic Nanorings
Wen Zhang, Stephan Haas
Ferromagnetic rings exhibit many novel physical phenomena with promise for potential applications. Here, we focus on switching processes which are fundamental properties of magneti…
Adaptation and Performance of the Cartesian Coordinates Fast Multipole Method for Nanomagnetic Simulations
Wen Zhang, Stephan Haas
An implementation of the fast multiple method (FMM) is performed for magnetic systems with long-ranged dipolar interactions. Expansion in spherical harmonics of the original FMM is…
Scaling Analysis and Application: Phase Diagram of Magnetic Nanorings and Elliptical Nanoparticles
Wen Zhang, Rohit Singh, Noah Bray-Ali +1
The magnetic properties of single-domain nanoparticles with different geometric shapes, crystalline anisotropies and lattice structures are investigated. A recently proposed scalin…
