Fabrication And Characterization Of High-Quality Nb/Al-AlO/Nb Cross-Type Josephson Tunnel Junctions Utilising CMP-based Planarisation Techniques
Alexander Stoll, Andreas Reifenberger, Daniel Hengstler +2
Josephson tunnel junctions (JJs) are the fundamental building blocks of today's most advanced superconducting electronic components, such as qubits and superconducting quantum inte…
Improved limit on the effective electron neutrino mass with the ECHo-1k experiment
Fabienne Adam, Felix Ahrens, Luis E. Ardila Perez +56
The effective electron neutrino mass can be determined by analyzing the endpoint region of the Ho electron capture spectrum, provided a measurement with high energy resolut…
Measuring Magnetic 1/f Noise in Superconducting Microstructures and the Fluctuation-Dissipation Theorem
Matthew Herbst, Andreas Fleischmann, Daniel Hengstler +5
The performance of superconducting devices like qubits, SQUIDs, and particle detectors is often limited by finite coherence times and 1/f noise. Various types of slow fluctuators i…
Development of a novel calorimetry setup based on metallic paramagnetic temperature sensors
Andreas Reifenberger, Andreas Reiser, Sebastian Kempf +2
We have developed a new micro-fabricated platform for the measurement of the specific heat of low heat capacity mg-sized metallic samples, such as superconductors, down to temperat…
Specific Heat of Holmium in Gold and Silver at Low Temperatures
Matthew Herbst, Andreas Reifenberger, Clemens Velte +10
The specific heat of dilute alloys of holmium in gold and in silver plays a major role in the optimization of low temperature microcalorimeters with enclosed , s…
Specific heat of K071Na0.29Fe2As2 at very low temperatures
A. Reifenberger, M. Hempel, P. Vogt +8
A commercially available calorimeter has been used to investigate the specific heat of a high-quality \kn\ single crystal. The addenda heat capacity of the calorimeter is determine…
Evidence of d-wave Superconductivity in K_(1-x)Na_xFe_2As_2 (x = 0, 0.1) Single Crystals from Low-Temperature Specific Heat Measurements
M. Abdel-Hafiez, V. Grinenko, S. Aswartham +20
From the measurement and analysis of the specific heat of high-quality K_(1-x)Na_xFe_2As_2 single crystals we establish the presence of large T^2 contributions with coefficients al…
