A self-referenced single-electron quantized-current source
Lukas Fricke, Michael Wulf, Bernd Kaestner +8
With the anticipated redefinition of the international system of units (SI) the base units will be linked to fundamental constants of nature [1]. As for the electrical base unit "A…
Characterization of Anomalous Pair Currents in Josephson Junction Networks
I. Ottaviani, M. Lucci, R. Menditto +8
Measurements performed on superconductive networks shaped in the form of planar graphs display anomalously large currents when specific branches are biased. The temperature depende…
Nanoscale multifunctional sensor formed by a Ni nanotube and a scanning Nb nanoSQUID
J. Nagel, A. Buchter, F. Xue +14
Nanoscale magnets might form the building blocks of next generation memories. To explore their functionality, magnetic sensing at the nanoscale is key. We present a multifunctional…
Reversal mechanism of an individual Ni nanotube simultaneously studied by torque and SQUID magnetometry
A. Buchter, J. Nagel, D. Rüffer +15
Using an optimally coupled nanometer-scale superconducting quantum interference device, we measure the magnetic flux originating from an individual ferromagnetic Ni nanotube attach…
Nb nano superconducting quantum interference devices with high spin sensitivity for operation in magnetic fields up to 0.5\,T
Roman Wölbing, Joachim Nagel, Tobias Schwarz +7
We investigate electric transport and noise properties of microstrip-type submicron direct current superconducting quantum interference devices (dc SQUIDs) based on Nb thin films a…
Bilayer Graphene Quantum Dot Defined by Topgates
André Müller, Bernd Kaestner, Frank Hohls +3
We investigate the application of nanoscale topgates on exfoliated bilayer graphene to define quantum dot devices. At temperatures below 500 mK the conductance underneath the groun…
