Exchange-mediated, non-linear, out-of-plane magnetic field dependence of the ferromagnetic vortex gyrotropic mode frequency driven by core deformation
Jasper P. Fried, Hans Fangohr, Mikhail Kostylev +1
We have performed micromagnetic simulations of the vortex gyrotropic mode resonance in a range of disk geometries subject to spatially uniform out-of-plane magnetic fields. For dis…
Electrical measurement of magnetic-field-impeded polarity switching of a ferromagnetic vortex core
Manu Sushruth, Jasper P. Fried, Abdelmadjid Anane +5
Vortex core polarity switching in NiFe disks has been evidenced using an all-electrical rectification scheme. Both simulation and experiments yield a consistent loss of the rectifi…
Resonance-based Detection of Magnetic Nanoparticles and Microbeads Using Nanopatterned Ferromagnets
Manu Sushruth, Junjia Ding, Jeremy Duczynski +7
Biosensing with ferromagnet-based magnetoresistive devices has been dominated by electrical detection of particle-induced changes to the devices' static magnetic configuration. The…
Frequency-based nanoparticle sensing over large field ranges using the ferromagnetic resonances of a magnetic nanodisc
Maximilian Albert, Marijan Beg, Dmitri Chernyshenko +4
Using finite element micromagnetic simulations, we study how resonant magnetisation dynamics in thin magnetic discs with perpendicular anisotropy are influenced by magnetostatic co…
Sensitivity Enhancement of Pd/Co Bi-layer Film for Hydrogen Gas Sensing using Perpendicular-to-Plane Ferromagnetic Resonance Configuration
Chris Lueng, Peter J. Metaxas, Mikhail Kostylev
Previously, it has been shown that the strength of the perpendicular magnetic anisotropy (PMA) of thin Palladium-Cobalt bi-layer films can be modified when hydrogen gas is absorbed…
Localized magnetic fields enhance the field-sensitivity of the gyrotropic resonance frequency of a magnetic vortex
Jasper Fried, Peter Metaxas
We have carried out micromagnetic simulations of the gyrotropic resonance mode of a magnetic vortex in the presence of spatially localized and spatially uniform out-of-plane magnet…
