Micromagnetic simulations of ferromagnetic rings [PDF]
Journal of Applied Physics, 2008 Thin nanomagnetic rings have generated interest for fundamental studies of magnetization reversal and also for their potential in various applications, particularly as magnetic memories. They are a rare example of a geometry in which an analytical solution for the rate of thermally induced magnetic reversal has been determined, in an approximation ...

Full Micromagnetic Numerical Simulations of Thermal Fluctuations [PDF]
IEEE Transactions on Magnetics, 2009 Thermal fluctuations for fine ferromagnetic particles are studied with the full micromagnetic analysis based on numerical integration of the spatially discretized Langevin-Landau-Lifshitz equation. These results can be used as a basis for the formulation of a standard problem to test the implementation of thermal fluctuations in numerical micromagnetic

Micromagnetic simulations of absoption spectra [PDF]
Journal of Magnetism and Magnetic Materials, 2006 Further development of a previously introduced method for numerically simulating magnetic spin waves is presented. Together with significant improvements in speed, the method now allows one to calculate the energy absorbed by the various modes excited by a position- and time-dependent H1 field in a ferromagnetic body of arbitrary shape in the presence ...

Micromagnetic simulations of magnetoelectric materials [PDF]
Journal of Applied Physics, 2011 Some magnetic materials show a magnetoelectric coupling between inhomogeneous magnetization patterns and electric polarization that is sufficiently strong to allow external control of magnetization structure by electric fields. Numerical simulations of “magnetoelectric” materials of this type require an extension of the standard micromagnetic model ...

Multiscale and multimodel simulation of Bloch point dynamics [PDF]
, 2013 We present simulation results on the structure and dynamics of micromagnetic point singularities with atomistic resolution. This is achieved by embedding an atomistic computational region into a standard micromagnetic algorithm. Several length scales are

Micromagnetic Simulations of Chaotic Ferromagnetic Nanofiber Networks [PDF]
Nanomaterials, 2020 Electrospinning can be used to create nanofibers with diameters of typically a few tens to a few hundred nanometers. While pure polymers are often electrospun, it is also possible to use polymer blends or to include nanoparticles. In this way, e.g., magnetic nanofiber networks can be created with a certain diameter distribution, random fiber ...
