Fluxoid fluctuations in mesoscopic superconducting rings
Julie A. Bert, Nicholas C. Koshnick, Hendrik Bluhm +1
Rings are a model system for studying phase coherence in one dimension. Superconducting rings have states with uniform phase windings that are integer multiples of 2 called flux…
Limits on Superconductivity-Related Magnetization in SrRuO and PrOsSb from Scanning SQUID Microscopy
Clifford W. Hicks, John R. Kirtley, Thomas M. Lippman +6
We present scanning SQUID microscopy data on the superconductors Sr2RuO4 (Tc = 1.5 K) and PrOsSb (Tc = 1.8 K). In both of these materials, superconductivity-related time…
Design concepts for an improved integrated scanning SQUID
Nicholas C. Koshnick, John R. Kirtley, Kathryn A. Moler
In this paper we discuss design concepts for increasing the spatial resolution, improving the sensitivity, and reducing the invasiveness in scanning Superconducting Quantum Interfe…
Spin-like susceptibility of metallic and insulating thin films at low temperature
Hendrik Bluhm, Julie A. Bert, Nicholas C. Koshnick +2
Susceptibility measurements of patterned thin films at sub-K temperatures were carried out using a scanning SQUID microscope that can resolve signals corresponding to a few hundred…
A Terraced Scanning Superconducting Quantum Interference Device Susceptometer with Sub-Micron Pickup Loops
Nicholas C. Koshnick, Martin E. Huber, Julie A. Bert +4
Superconducting Quantum Interference Devices (SQUIDs) can have excellent spin sensitivity depending on their magnetic flux noise, pick-up loop diameter, and distance from the sampl…
Fluctuation Superconductivity in Mesoscopic Aluminum Rings
Nicholas C. Koshnick, Hendrik Bluhm, Martin E. Huber +1
Fluctuations are important near phase transitions, where they can be difficult to describe quantitatively. Superconductivity in mesoscopic rings is particularly intriguing because…
