Fabrication and micromagnetic modeling of barium hexaferrite thin films by RF magnetron sputtering

open access: yesResults in Physics, 2018
The synthesis and characterization of thin M-type barium hexaferrite (BaFe12O19 or BaM) films on silicon are reported. Multilayer in situ technique was employed to anneal the films at 850–900 °C for 10 min.

Comparative Modeling of Frequency Mixing Measurements of Magnetic Nanoparticles Using Micromagnetic Simulations and Langevin Theory

open access: yesNanomaterials, 2021
Dual frequency magnetic excitation of magnetic nanoparticles (MNP) enables enhanced biosensing applications. This was studied from an experimental and theoretical perspective: nonlinear sum-frequency components of MNP exposed to dual-frequency magnetic ...

Unidirectional sub-100 ps magnetic vortex core reversal

open access: yes, 2014
The magnetic vortex structure, an important ground state configuration in micron and sub-micron sized ferromagnetic thin film platelets, is characterized by a curling in-plane magnetization and, in the center, a minuscule region with out-of-plane ...

Embedded Object-Oriented Micromagnetic Frame (OOMMF) for More Flexible Micromagnetic Simulations [PDF]

open access: yesJournal of Magnetics, 2016
We developed an embedded Object-Oriented Micromagnetic Frame (OOMMF) script schemes for more flexible simulations for complex and dynamic mircomagnetic behaviors. The OOMMF can be called from any kind of softwares by system calls, and we can interact with OOMMF by updating the input files for next step from the output files of the previous step of ...

Micromagnetic Simulation of Strain-Assisted Current-Induced Magnetization Switching

open access: yesAdvances in Condensed Matter Physics, 2016
We investigated the effect of substrate misfit strain on the current-induced magnetization switching in magnetic tunnel junctions by combining micromagnetic simulation with phase-field microelasticity theory.

Ptychographic imaging and micromagnetic modeling of thermal melting of nanoscale magnetic domains in antidot lattices

open access: yesAIP Advances, 2020
Antidot lattices are potential candidates to act as bit patterned media for data storage as they are able to trap nanoscale magnetic domains between two adjacent holes.

Proposal for a micromagnetic standard problem for materials with Dzyaloshinskii–Moriya interaction

open access: yesNew Journal of Physics, 2018
Understanding the role of the Dzyaloshinskii–Moriya interaction (DMI) for the formation of helimagnetic order, as well as the emergence of skyrmions in magnetic systems that lack inversion symmetry, has found increasing interest due to the significant ...
