Magnetism

Invited Talk

In the last decade the physics of spin waves has regained interest in the emerging field of magnonics. In a magnonic device, the collective precession motion of spins in a ferromagnet permits to process information at low power consumption and high operation speed in a wide frequency range from GHz to THz. Spin waves present two important features: their frequency can be easily varied by...

28. Current-Induced Skyrmion Dynamics and Diffusion

Magnetism

Contributed Talk

Magnetic skyrmions, nanoscale chiral spin textures with particle-like behavior, are promising candidates for information storage and unconventional computing due to their robustness and efficient current-driven motion [1-3]. In Ta/CoFeB/MgO multilayers, we investigate the transition of current-driven skyrmion motion from creep, through depinning, to the viscous flow regime driven by a...

77. Strain-induced Control on Topological Magnetic Textures in Antiskyrmion Hosting Material

Magnetism

Contributed Talk

In non-centrosymmetric crystal structures with $D_{2d}$ or $S_4$ symmetry, anisotropic Dzyaloshinskii-Moriya interaction (DMI) stabilizes antiskyrmions which was recently confirmed experimentally [1,2]. In these materials, easy-axis anisotropy additionally stabilizes skyrmions and non-topological bubbles in certain ranges of external magnetic fields and lamella thicknesses. The competition...

49. Erbium-doped materials for microwave-to-optical interfaces in superconducting quantum networks

Karolina Weber (Max-Planck-Institut für Quantenoptik, Technische Universität München)

Fundamentals of quantum systems

Contributed Talk

Future quantum networks require interfaces that connect quantum processors over long distances. Superconducting quantum circuits are a leading platform for quantum computing, but operate with microwave-frequency signals that cannot be efficiently transmitted through optical-fiber networks (1, 2). Optical photons, by contrast, are well suited for low-loss communication over long distances and...
