Bridging atomic and mesoscopic length scales with Replica Scanning Tunneling Microscopy: Visualizing the atomic lattice of UTe and the atomic scale superconducting gap modulations of FeSe close to micron length scales
Miguel Águeda Velasco, Jose D. Bermúdez-Pérez, Pablo García Talavera +16
Scanning Tunneling Microscopy is a cornerstone technique for visualizing the electronic density of states with atomic resolution (typically below 0.1 nm). While the field of view o…
Direct observation of vortex liquid droplets in the iron pnictide superconductor CaKAsFe at _c$
Oscar Bou Marqués, Jose A. Moreno, Pablo García Talavera +7
Type-II superconductors under magnetic fields are in a quantum coherent non-dissipative state as long as vortices remain pinned. Dissipation appears when vortices depin, eventually…
Competition between the modification of intrinsic superconducting properties and the pinning landscape under external pressure in CaKFeAs single crystals
Shuyuan Huyan, Nestor Haberkorn, Mingyu Xu +2
Measurements of low field magnetization, trapped flux magnetization and 5 K flux creep in single crystal of CaKFeAs under pressure up to 7.5 GPa in a diamond pressure cell…
Spatially - resolved study of the Meissner effect in superconductors using NV-centers-in-diamond optical magnetometry
N. M. Nusran, K. R. Joshi, K. Cho +7
Non-invasive magnetic field sensing using optically - detected magnetic resonance of nitrogen-vacancy (NV) centers in diamond was used to study spatial distribution of the magnetic…
Influence of the multiband sign changing superconductivity on the vortex cores and on vortex pinning in the new stoichiometric high Tc CaKFe4As4
A. Fente, W. R. Meier, T. Kong +5
We study the superconducting density of states and vortex lattice of single crystals of CaKFeAs using a scanning tunneling microscope (STM). This material has a critical te…
Scanning Tunneling Microscopy in the superconductor LaSb2
J. A. Galvis, H. Suderow, S. Vieira +2
We present very low temperature (0.15 K) scanning tunneling microscopy and spectroscopy experiments in the layered superconductor LaSb. We obtain topographic microscopy images…
Superconducting order parameter in nonmagnetic borocarbides RNiBC (R=Y, Lu) probed by point-contact Andreev reflection spectroscopy
X. Lu, W. K. Park, S. Yeo +5
We report on the measurements of the superconducting order parameter in the nonmagnetic borocarbides LuNiBC and YNiBC. Andreev conductance spectra are obtained from…
Titanium additions to MgB2 conductors
N. E. Anderson, W. E. Straszheim, S. L. Bud'ko +3
A series of doping experiments are reported for MgB2 conductors that have been synthesized using doped boron fibers prepared by chemical vapor deposition(CVD) methods. Undoped MgB2…
Magneto-optical studies of the uniform critical state in bulk MgB2
A. A. Polyanskii, A. Gurevich, J. Jiang +6
We present a detailed magneto-optical investigation of the magnetic flux penetration in polycrystalline MgB2 slabs made by direct reaction of B and Mg. Our results unambiguously in…
