Electrical spectroscopy of forward volume spin waves in perpendicularly magnetized materials
M. Sushruth, M. Grassi, K. Ait-Oukaci +8
We study the potential of all-electrical inductive techniques for the spectroscopy of propagating forward volume spin waves. We develop a one-dimensional model to account for the e…
Chirality-mediated bistability and strong frequency downshifting of the gyrotropic resonance of a dynamically de-stiffened magnetic vortex
Manu Sushruth, Jasper Fried, Abdelmadjid Anane +4
We demonstrate an enhanced, bidirectional, in-plane magnetic field tuning of the gyrotropic resonance frequency of a magnetic vortex within a disk by introducing a flat edge. When…
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…
Sensing magnetic nanoparticles using nano-confined ferromagnetic resonances in a magnonic crystal
Peter Metaxas, Manu Sushruth, Ryan Begley +8
We demonstrate the use of the magnetic-field-dependence of highly spatially confined, GHz-frequency ferromagnetic resonances in a ferromagnetic nanostructure for the detection of a…
