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…
Scanning Tunneling Spectroscopy and Vortex Imaging in the Iron-Pnictide Superconductor BaFeCoAs
Yi Yin, M. Zech, T. L. Williams +4
We present an atomic resolution scanning tunneling spectroscopy study of superconducting BaFeCoAs single crystals in magnetic fields up to . At…
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…
Destruction of antinodal state coherence via `checkerboard' charge ordering in strongly underdoped superconducting BSCCO-2212
K. McElroy, D. -H. Lee, J. E. Hoffman +6
Microscopy (STM). At all dopings, the low energy density-of-states modulations are analyzed according to a simple model of quasiparticle interference and found to be consistent wit…
Homogenous nodal superconductivity coexisting with inhomogeneous charge order in strongly underdoped Bi-2212
K. McElroy, D. -H. Lee, J. E. Hoffman +6
We use novel STM techniques in concert to study the doping dependence of electronic structure in Bi-2212. At all dopings, the low energy states are relatively homogenous except for…
