Generation of Bloch Points with Controlled Spin Texture Using Geometrical Boundary Conditions

Naëmi Leo, Daniel Wolf, Alicia Estela Herguedas Alonso +16

Bloch points are three-dimensional topological singularities in magnetization that play a key role in topological transformations of spin textures, such as skyrmion creation or ann…

Geometric dependence of exchange bias in tilted three-dimensional CoFe/IrMn microwires

Balram Singh, Aman Singh, Stefan Mikulik +3

The exchange bias (EB) effect, arising from interfacial coupling between ferromagnetic (FM) and antiferromagnetic (AF) layers, induces a unidirectional magnetic anisotropy and unde…

Magnetization reversal mechanism of double-helix nanowires probed by dark-field magneto-optical Kerr effect

Takeaki Gokita, Jakub Jurczyk, Naëmi Leo +8

Double-helix (DH) nanowires provide a platform to study the influence of geometric chirality on spin chirality. Their three-dimensional (3D) helical architecture and tunable inter-…

Nucleation of magnetic skyrmions on curvilinear surfaces using local magnetic fields

Sabri Koraltan, Joe Sunny, Emily Darwin +11

Magnetic skyrmions stabilized by interfacial Dzyaloshinskii-Moriya interactions (DMI) are promising candidates for applications in memory, logic, and neuromorphic computing. Beyond…

Fractional Skyrmion Tubes in Chiral-Interfaced Three-Dimensional Magnetic Nanowires

John Fullerton, Naëmi Leo, Jakub Jurczyk +9

Magnetic skyrmions are chiral spin textures with rich physics and great potential for unconventional computing. Typically, skyrmions form in bulk crystals with reduced symmetry or…
