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…
