Micromagnetic simulation of iron nanorings

Journal of Magnetism and Magnetic Materials, 2005
Abstract We performed a systematic study of the magnetic properties of iron nanorings with 80 nm external diameter varying the thickness in the framework of micromagnetic theory. Hysteresis loops were determined in an applied magnetic field ranging from −800 to 800 mT. The behavior of coercive field as a function of the ratio of the inner d

Micromagnetic Simulations in Magnonics

2012
We review the use of numerical micromagnetic simulations (“micromagnetics”) for investigations in magnonics, the study of spin waves and their quanta – magnons. We argue that, when used with suitable post-processing tools, micromagnetics provide the power and flexibility necessary both for interpretation of complex magnonic phenomena observed in ...

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

Techniques in micromagnetic simulation and analysis

Journal of Physics D: Applied Physics, 2017
Abstract Advances in nanofabrication now allow us to manipulate magnetic material at micro- and nanoscales. As the steps of design, modelling and simulation typically precede that of fabrication, these improvements have also granted a significant boost to the methods of micromagnetic simulations (MSs) and analyses.

Micromagnetic recording process simulation

IEEE Transactions on Magnetics, 1987
A dynamic model is introduced for simulating the magnetic recording process. This model has high spatial (particulate level) and temporal ( \sim10^{-9} second) resolution. The theory includes head saturation, image charge, particle magnetostatic interaction, and particle anisotropy. Several applications to barium ferrite media are presented.

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.

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.
