Vortex-core spectroscopy of -wave cuprate high-temperature superconductors
Ivan Maggio-Aprile, Tejas Parasram Singar, Christophe Berthod +3
The mechanism of high-temperature superconductivity remains one of the great challenges of contemporary physics. Here, we review efforts to image the vortex lattice in copper oxide…
Skyrmion-(Anti)Vortex Coupling in a Chiral Magnet-Superconductor Heterostructure
A. P. Petrović, M. Raju, X. Y. Tee +9
We report experimental coupling of chiral magnetism and superconductivity in [IrFeCoPt]/Nb heterostructures. The stray field of skyrmions with radius ~50nm is sufficient to nucleat…
Wang-MacDonald d-wave vortex cores observed in heavily overdoped BiSrCaCuO
Tim Gazdić, Ivan Maggio-Aprile, Genda Gu +1
Low magnetic field scanning tunneling spectroscopy of individual Abrikosov vortices in heavily overdoped BiSrCaCuO unveils a clear d-wave electronic structure o…
Observation of Caroli-de Gennes-Matricon Vortex States in YBaCuO
Christophe Berthod, Ivan Maggio-Aprile, Jens Bruér +2
The copper oxides present the highest superconducting temperature and properties at odds with other compounds, suggestive of a fundamentally different superconductivity. In particu…
Revisiting the vortex-core tunnelling spectroscopy in YBaCuO
Jens Bruér, Ivan Maggio-Aprile, Nathan Jenkins +5
The observation by scanning tunnelling spectroscopy (STS) of Abrikosov vortex cores in the high-temperature superconductor YBaCuO (Y123) has revealed a robust pair…
Scanning tunneling spectroscopy of high-temperature superconductors
Oystein Fischer, Martin Kugler, Ivan Maggio-Aprile +2
Tunneling spectroscopy played a central role in the experimental verification of the microscopic theory of superconductivity in the classical superconductors. Initial attempts to a…
Unusual dependence of vortex core states on the superconducting gap in BiSrCaCuO
B. W. Hoogenboom, K. Kadowaki, B. Revaz +3
We present a scanning tunneling spectroscopy study on quasiparticle states in vortex cores in BiSrCaCuO. The energy of the observed vortex core states shows an…
