Strong Charge-Photon Coupling in Planar Germanium Enabled by Granular Aluminium Superinductors
Marián Janík, Kevin Roux, Carla Borja Espinosa +11
High kinetic inductance superconductors are gaining increasing interest for the realisation of qubits, amplifiers and detectors. Moreover, thanks to their high impedance, quantum b…
Control of vortex chirality in a symmetric ferromagnetic ring using ferromagnetic nanoelement
Uladzislau Makartsou, Mathieu Moalic, Mateusz Zelent +2
Controlling the vortex chirality in ferromagnetic nanodots and nanorings has been a topic of investigation for the last few years. Many control methods have been proposed and it ha…

Krzysztof Szulc, Piotr Graczyk, Michał Mruczkiewicz +2
In magnonics, an emerging branch of wave physics characterized by low-energy consumption, it is highly desirable to realize circuit elements within the scope of spin-wave computing…
Bimeron Clusters in Chiral Antiferromagnets
X. Li, L. Shen, Y. Bai +12
A mgnetic bimeron is an in-plane topological counterpart of a magnetic skyrmion. Despite the topological equivalence, their statics and dynamics could be distinct, making them attr…
Controlled motion of skyrmions in a magnetic antidot lattice
J. Feilhauer, S. Saha, J. Tobik +3
Future spintronic devices based on skyrmions will require precise control of the skyrmion motion. We show that this goal can be achieved through the use of magnetic antidot arrays.…
Formation of Néel Type Skyrmions in an Antidot Lattice with Perpendicular Magnetic Anisotropy
S. Saha, M. Zelent, S. Finizio +8
Magnetic skyrmions are particle-like chiral spin textures found in a magnetic film with out-of-planeanisotropy and are considered to be potential candidates as information carriers…
