Our vision is to trigger a revolution in low-power information and communication technologies in an energy-efficient society.

QuSpin´s objective is to develop the basic science that uses quantum entities such as the electron spin as information carriers in radically different ways. We aim at groundbreaking basic research that is crucial to the  development of fast, high-capacity, material systems and tools for smaller and more power-efficient electronic devices.

Going beyond the Chandrasekhar-Clogston limit in a flatband superconductor

Phys. Rev. B .2022 ;Volum 105. Ghanbari, Atousa; Erlandsen, Eirik; Sudbø, Asle; Linder, Jacob.
Abstract

The Chandrasekhar-Clogston limit normally places stringent conditions on the magnitude of the magnetic field that can coexist with spin-singlet superconductivity, restricting the critical induced Zeeman shift to a fraction of the superconducting gap...

Magnetotransport Study of van der Waals CrPS4/(Pt, Pd) Heterostructures: Spin-Flop Transition and Room-Tempearture Anomalous Hall Effect

Phys. Rev. Applied 17, (064038) Rui Wu, Andrew Ross, Shilei Ding, Yuxuan Peng, Fangge He, Yi Ren, Romain Lebrun, Yong Wu, Zhen Wang, Jinbo Yang, Arne Brataas, and Mathias Kläui.
Abstract

We study magnetotransport in heterostructures composed of the van der Waals antiferromagnet CrPS4 and the heavy metals Pt and Pd. In both types of devices, the transverse resistance (Rxy) signal reveals the spin-flop transition of CrPS4 and a strong anomalous Hall effect at temperatures up to 300 K...

Detection of Topological Spin Textures via Nonlinear Magnetic Responses

Nano Lett. 2022, 22, 1, 14–21 Mariia Stepanova, Jan Masell, Erik Lysne, Peggy Schoenherr, Laura Köhler, Michael Paulsen, Alireza Qaiumzadeh, Naoya Kanazawa, Achim Rosch, Yoshinori Tokura, Arne Brataas, Markus Garst, and Dennis Meier.
Abstract

Topologically nontrivial spin textures, such as skyrmions and dislocations, display emergent electrodynamics and can be moved by spin currents over macroscopic distances. These unique properties and their nanoscale size make them excellent candidates for the development of next-generation race-track memory and unconventional computing. A major challenge for these applications...
