Micromagnetic simulation of taenite particles

2021
<p></p><div> <div> <div>The cloudy zone (CZ), an intergrowth structure of Fe-rich and Ni-rich phases that forms during slow cooling of iron meteorites are potential recorders of  their parent body’s thermal and magnetic history.

Micromagnetic modeling simulations and applications

2006 17th International Zurich Symposium on Electromagnetic Compatibility, 2006
The advancement in micro and nano-scale technologies demands in depth understanding of magnetic behaviors. For example, as the ever increasing need for high capacity data storage continuously pushes the boundaries of magnetic recording technology to the physical limits, detailed analysis of the magnetic properties becomes necessary. It is expected that

Micromagnetic simulation of an antiferromagnetic particle

Computational Materials Science, 2015
Abstract A continuum micromagnetic model is derived, describing an antiferromagnet. Using the finite element method, magnetization curves are calculated for a spherical uniaxial particle, varying the particle’s size and the anisotropy field strength. Different magnetization processes appear by increasing the size of the particle.

Micromagnetic simulation of precessional switching

Physica B: Condensed Matter, 2006
Abstract Precessional switching of information bits may prove to be an alternative of traditional “hysteretic” switching in magnetic memory devices. The experimental studies of this new “write-in” process have manifested unwanted fluctuations, which may pose a limit to its technological applicability.

Micromagnetic simulations of transverse recording

IEEE Transactions on Magnetics, 1991
A hierarchical micromagnetic model of longitudinal thin film media has been employed to investigate the high density performance of transverse recording. The model predicts that linear densities up to 12 bits/ mu m (300 kfci) can be supported on media of 750 Oe coercivity.

Micromagnetic Simulation of Switching Events

2007
Magnetic switching of small particles, thin film elements and magnetic nanowires becomes increasingly important in magnetic storage and magneto electronic devices. Micromagnetic switching events are studied using a hybrid finite element / boundary element method.

High-performance micromagnetic simulations using OpenCL

Proceedings of the International Workshop on OpenCL, 2020
We study the possibility to achieve optimal performance in micromagnetic simulation using GPGPU OpenCL calculations. We take into account several possibilities to accelerate using GPU-specific optimizations and reuse of external data arrays, and achieve up to 70% of theoretical maximum.

Micromagnetic Simulation of the imaginary part of the transverse susceptibility

IEEE Transactions on Magnetics, 2005
The transverse susceptibility (TS) signal of interacting magnetic systems with volume and anisotropy fields distribution was presented. The temperature dependence of TS was studied using the stochastic Landau-Lifshitz-Gilbert equation. Temperature has affected the oscillation of the moment and the magnitude of the phase shifts.

Micromagnetic Simulation of Recording Write Heads a Comparison of Various Micromagnetic Software

IEEE Transactions on Magnetics, 2012
The performance of three micromagnetic software were compared: (a) originally developed by Hitachi and refined at Kogakuin Univeristy and Niigata Institute of Technology, (b) developed by Fujitsu, and (c) Magpar, a free, public domain software. A perpendicular write head was modeled to compare the performance of these software.

Micromagnetic simulation method with N1.5 scaling

Journal of Applied Physics, 1999
A thin permalloy film with dimensions of 1 μm×2 μm×20 nm was simulated with a new three-dimensional method. The method is designed in such a way that the computing time scales roughly as N1.5 in the number N of discretization elements used to describe the system.
