Cryogenic fiber-coupled electro-optic characterization platform for high-speed photodiodes
Shekhar Priyadarshi, Hao Tian, Alexander Fernandez Scarioni +5
We have developed a cryogenic characterization platform for ultrafast photodiodes, whose time domain responses are extracted by electro-optic sampling using femtosecond laser pulse…
High-Q magnetic levitation and control of superconducting microspheres at millikelvin temperatures
Joachim Hofer, Rudolf Gross, Gerard Higgins +11
We report the levitation of a superconducting lead-tin sphere with 100 micrometer diameter (corresponding to a mass of 5.6 micrograms) in a static magnetic trap formed by two coils…
Combining Electron Spin Resonance Spectroscopy with Scanning Tunneling Microscopy at High Magnetic Fields
Robert Drost, Maximilian Uhl, Piotr Kot +8
Magnetic media remain a key in information storage and processing. The continuous increase of storage densities and the desire for quantum memories and computers pushes the limits…
Driving a low critical current Josephson junction array with a mode-locked laser
J. Nissila, T. Fordell, K. Kohopaa +11
We demonstrate the operation of Josephson junction arrays (JJA) driven by optical pulses generated by a mode-locked laser and an optical time-division multiplexer. A commercial pho…
Towards ultra-sensitive SQUIDs based on sub-micrometer-sized Josephson Junctions
Jan-Hendrik Storm, Oliver Kieler, Rainer Körber
We recently demonstrated a 1-order axial gradiometer SQUID system, which is operated in a liquid He dewar with negligible noise contribution. The achieved close to…
Three-Axis Vector Nano Superconducting Quantum Interference Device
M. J. Martínez-Pérez, D. Gella, B. Müller +6
We present the design, realization and performance of a three-axis vector nano Superconducting QUantum Interference Device (nanoSQUID). It consists of three mutually orthogonal SQU…
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…
