Characterizing dielectric properties of ultra-thin films using superconducting coplanar microwave resonators
Nikolaj G. Ebensperger, Benedikt Ferdinand, Dieter Koelle +3
We present an experimental approach for cryogenic dielectric measurements on ultra-thin insulating films. Based on a coplanar microwave waveguide design we implement superconductin…
Simultaneous observation of high order multiple quantum coherences at ultralow magnetic fields
K. Buckenmaier, K. Scheffler, M. Plaumann +8
We present a method for the simultaneous observation of heteronuclear multi-quantum coherences (up to the 3rd order), which give an additional degree of freedom for ultralow magnet…
Ultradense Tailored Vortex Pinning Arrays in Superconducting YBaCuO Thin Films Created by Focused He Ion Beam Irradiation for Fluxonics Applications
Bernd Aichner, Benedikt Müller, Max Karrer +9
Magnetic fields penetrate a type-II superconductor as magnetic flux quanta, called vortices. In a clean superconductor they arrange in a hexagonal lattice, while by adding periodic…
Josephson junctions and SQUIDs created by focused helium ion beam irradiation of YBaCuO
B. Müller, M. Karrer, F. Limberger +6
By scanning with a focused He ion beam (He-FIB) across YBaCuO (YBCO) thin film microbridges, we create Josephson barriers with critical current dens…
