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…
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…
Controlled Manipulation of Individual Vortices in a Superconductor
E. W. J. Straver, J. E. Hoffman, O. M. Auslaender +2
We report controlled local manipulation of single vortices by low temperature magnetic force microscope (MFM) in a thin film of superconducting Nb. We are able to position the vort…
Persistent currents in normal metal rings
Hendrik Bluhm, Nicholas C. Koshnick, Julie A. Bert +2
The authors have measured the magnetic response of 33 individual cold mesoscopic gold rings, one ring at a time. The response of some sufficiently small rings has a component that…
