Colossal topological Hall effect at the transition between isolated and lattice-phase interfacial skyrmions
M. Raju, A. P. Petrović, A. Yagil +8
The topological Hall effect is used extensively to study chiral spin textures in various materials. However, the factors controlling its magnitude in technologically-relevant thin…
Magnetization Reversal Signatures of Hybrid and Pure Néel Skyrmions in Thin Film Multilayers
Nghiep Khoan Duong, Riccardo Tomasello, M. Raju +4
We report a study of the magnetization reversals and skyrmion configurations in two systems - Pt/Co/MgO and Ir/Fe/Co/Pt multilayers, where magnetic skyrmions are stabilized by a co…
Microwave resonances of magnetic skyrmions in thin film multilayers
Bhartendu Satywali, Volodymyr P. Kravchuk, Liqing Pan +6
Non-collinear magnets exhibit a rich array of dynamic properties at microwave frequencies. They can host nanometre-scale topological textures known as skyrmions, whose spin resonan…
Skyrmion-(Anti)Vortex Coupling in a Chiral Magnet-Superconductor Heterostructure
A. P. Petrović, M. Raju, X. Y. Tee +9
We report experimental coupling of chiral magnetism and superconductivity in [IrFeCoPt]/Nb heterostructures. The stray field of skyrmions with radius ~50nm is sufficient to nucleat…
Stabilizing zero-field skyrmions in Ir/Fe/Co/Pt thin film multilayers by magnetic history control
Nghiep Khoan Duong, M. Raju, A. P. Petrovic +3
We present a study of the stability of room-temperature skyrmions in [Ir/Fe/Co/Pt] thin film multilayers, using the First Order Reversal Curve (FORC) technique and magnetic force m…
Gyrotropic resonance of individual Néel skyrmions in Ir/Fe/Co/Pt multilayers
Bhartendu Satywali, Fusheng Ma, Shikun He +5
Magnetic skyrmions are nanoscale spin structures recently discovered at room temperature (RT) in multilayer films. Employing their novel topological properties towards exciting tec…
Sub-100 nm Skyrmions at Zero Magnetic Field in Ir/Fe/Co/Pt Nanostructures
Pin Ho, Anthony K. C. Tan, S. Goolaup +5
Magnetic skyrmions are chiral spin structures that have recently been observed at room temperature (RT) in multilayer thin films. Their topological stability should enable high sca…
Chiral magnetic textures in Ir/Fe/Co/Pt multilayers: Evolution and topological Hall signature
M. Raju, A. Yagil, Anjan Soumyanarayanan +4
Skyrmions are topologically protected, two-dimensional, localized hedgehogs and whorls of spin. Originally invented as a concept in field theory for nuclear interactions, skyrmions…
