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…
Mechanics of Individual, Isolated Vortices in a Cuprate Superconductor
Ophir M. Auslaender, Lan Luan, Eric W. J. Straver +7
Superconductors often contain quantized microscopic whirlpools of electrons, called vortices, that can be modeled as one-dimensional elastic objects. Vortices are a diverse playgro…
Limits on the Superconducting Order Parameter in NdFeAsOF from Scanning SQUID Microscopy
C. W. Hicks, T. M. Lippman, M. E. Huber +3
Identifying the symmetry of the superconducting order parameter in the recently-discovered ferro-oxypnictide family of superconductors, RFeAsOF, where is a rare e…
Two-dimensional vortex behavior in highly underdoped YBa_2Cu_3O_{6+x} observed by scanning Hall probe microscopy
J. W. Guikema, Hendrik Bluhm, D. A. Bonn +3
We report scanning Hall probe microscopy of highly underdoped superconducting YBa_2Cu_3O_{6+x} with T_c ranging from 5 to 15 K which showed distinct flux bundles with less than one…
