Yu-Shiba-Rusinov tips: imaging spins at the atomic scale with full magnetic sensitivity
Felix Küster, Souvik Das, Stuart S. P. Parkin +1
Measurements of magnetic properties at the atomic scale require probes capable of combining high spatial resolution with spin sensitivity. Spin-polarized scanning tunneling microsc…
Non-Majorana modes in diluted spin chains proximitized to a superconductor
Felix Küster, Sascha Brinker, Richard Hess +5
Spin chains proximitized with superconducting condensates have emerged as one of the most promising platforms for the realization of Majorana modes. Here, we craft diluted spin cha…
Long range and highly tunable interaction between local spins coupled to a superconducting condensate
Felix Küster, Sascha Brinker, Samir Lounis +2
Interfacing magnetism with superconducting condensates is rapidly emerging as a viable route for the development of innovative quantum technologies. In this context, the developmen…
Correlating Josephson supercurrents and Shiba states in quantum spins unconventionally coupled to superconductors
Felix Küster, Ana M. Montero, Filipe S. M. Guimarares +4
Local spins coupled to superconductors give rise to several emerging phenomena directly linked to the competition between Cooper pair formation and magnetic exchange. These effects…
Competing energy scales in topological superconducting heterostructures
Yunyi Zang, Felix Küster, Jibo Zhang +6
Artificially engineered topological superconductivity has emerged as a viable route to create Majorana modes, exotic quasiparticles which have raised great expectations for storing…
On the preparation and electronic properties of clean superconducting Nb(110) surfaces
Artem B. Odobesko, Soumyajyoti Haldar, Stefan Wilfert +7
We have studied cleaning procedures of Nb(110) by verifying the surface quality with low-energy electron diffraction, Auger electron spectroscopy, and scanning tunneling microscopy…
