Stability of (Active) Bilayer Skyrmions in Synthetic Antiferromagnets
Rai M. Menezes, Clecio C. de Souza Silva
Synthetic antiferromagnetic (SAF) skyrmions are nanoscale composite textures that exhibit high-speed, Hall-free current-driven motion and recently demonstrated self-propulsion. The…
Many-body skyrmion interactions in helimagnets
N. P. Vizarim, J. C. Bellizotti Souza, Raí M. Menezes +3
Many-body interactions strongly influence the structure, stability, and dynamics of condensed-matter systems, from atomic lattices to interacting quasi-particles such as supercondu…
Skyrmion Lattice Manipulation with Electric Currents and Thermal Gradients in MnSi
N. Chalus, A. W. D. Leishman, R. M. Menezes +11
The skyrmion lattice (SkL) in MnSi was studied using small-angle neutron scattering and under the influence of a radial electric current in a Corbino geometry. In response to the a…
Skyrmion blinking from the conical phase
Rai M. Menezes, Milorad V. Milosevic
While the transition between skyrmionic and non-topological states has been widely explored as a bit operation for information transport and storage in spintronic devices, the ultr…
Stacking-dependent topological magnons in bilayer CrI
M. Soenen, C. Bacaksiz, R. M. Menezes +1
Motivated by the potential of atomically-thin magnets towards tunable high-frequency magnonics, we detail the spin-wave dispersion of bilayer CrI. We demonstrate that the magno…
Towards Magnonic Logic and Neuromorphic Computing: Controlling Spin-Waves by Spin-Polarized Current
Raí M. Menezes, Jeroen Mulkers, Clécio C. de Souza Silva +2
Spin-waves (magnons) are among the prime candidates for building fast yet energy-efficient platforms for information transport and computing. We here demonstrate theoretically and…
Tailoring High-Frequency Magnonics in Monolayer Chromium Trihalides
Raí M. Menezes, Denis Šabani, Cihan Bacaksiz +2
Monolayer chromium trihalides, the archetypal two dimensional (2D) magnetic materials, are readily suggested as a promising platform for high frequency magnonics. Here we detail th…
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…
Distinctive magnetic properties of CrI3 and CrBr3 monolayers caused by spin-orbit coupling
C. Bacaksiz, D. Šabani, R. M. Menezes +1
After the discovery of magnetism in monolayer CrI3, the magnetic properties of different 2D materials from the chromium-trihalide family are intuitively assumed to be similar, yiel…
Topological energy barrier for skyrmion lattice formation in MnSi
A. W. D. Leishman, R. M. Menezes, G. Longbons +8
We report the direct measurement of the topological skyrmion energy barrier through a hysteresis of the skyrmion lattice in the chiral magnet MnSi. Measurements were made using sma…
Spin textures in chiral magnetic monolayers with suppressed nearest-neighbor exchange
Raí M. Menezes, Clécio C. de Souza Silva, Milorad V. Milošević
High tunability of two dimensional magnetic materials (by strain, gating, heterostructuring or otherwise) provides unique conditions for studying versatile magnetic properties and…
