Single-crystalline CrSb(0001) thin films grown by dc magnetron co-sputtering
S. P. Bommanaboyena, C. Müller, M. Jarošová +15
The recent discovery of altermagnetism has sparked renewed interest in the growth of epitaxial films of the NiAs-phase polymorph of CrSb. This paper describes the magnetron sputter…
Unconventional relativistic spin polarization of electronic bands in an altermagnet
A. Dal Din, D. A. Usanov, L. Å mejkal +22
Altermagnetism is a recently identified phase with a d, g or i-wave spin symmetry of magnetic ordering. Its discovery opens new research fronts at intersections of magnetism and sp…
An InAsSb surface quantum well with in-situ deposited Nb as a platform for semiconductor-superconductor hybrid devices
Sjoerd Telkamp, Zijin Lei, Tommaso Antonelli +7
We present a novel semiconductor-superconductor hybrid material based on a molecular beam epitaxially grown InAsSb surface quantum well with an in-situ deposited Nb top layer. Rela…
High-temperature growth of ultra thin NbTiN films on lithium niobate for integrated single photon detection
Sjoerd Telkamp, Odiel Hooybergs, Myriam Rihani +9
Lithium niobate-on-insulator (LNOI) is an emerging photonic platform with high potential for scalable quantum information processing due to its strong second-order nonlinearity. Ho…
Voltage-tunable field-free Josephson diode
Sjoerd Telkamp, Junting Zhao, Saulius VaitiekÄnas
We report a gate-tunable Josephson diode effect in hybrid nanowire junctions consisting of a spin-orbit-coupled semiconductor core coated with epitaxial ferromagnetic insulator and…
Quench switching of Mn2As
Kamil OlejnÃk, ZdenÄk KaÅ¡par, Jan ZubÃ¡Ä +10
We demonstrate that epitaxial thin film antiferromagnet Mn2As exhibits the quench-switching effect, which was previously reported only in crystallographically similar antiferromagn…
