Phonon-mediated anisotropic superconductivity in the Y and Lu nickel borocarbides

, 2002
We present scanning tunneling spectroscopy and microscopy measurements at low temperatures in the borocarbide materials RNi2B2C (R=Y, Lu). The characteristic strong coupling structure due to the pairing interaction is unambiguously resolved in the ...

Supercurrent on a vortex core in 2H-NbSe$_2$: current driven scanning tunneling spectroscopy [PDF]

, 2013
We report current driven scanning tunneling spectroscopy (CDSTS) measurements at very low temperatures on vortices in 2H-NbSe2. We find that a current produces an increase of the density of states at the Fermi level in between vortices, and a reduction ...

When do citizen scientists record biodiversity? Non‐random temporal patterns of recording effort and associated factors

People and Nature, Volume 7, Issue 4, Page 860-870, April 2025.
Abstract Citizen science data are increasingly used for ecological research, biodiversity conservation and monitoring. However, these data often present significant analytical challenges due to uneven recording efforts by citizen scientists. Biases caused by intra‐annual differences in levels of recording activity can be particularly severe, hindering ...

Evolution of the local superconducting density of states in ErRh$_4$B$_{4}$ close to the ferromagnetic transition

, 2009
We present local tunneling spectroscopy experiments in the superconducting and ferromagnetic phases of the reentrant superconductor ErRh$_4$B$_{4}$. The tunneling conductance curves jump from showing normal to superconducting features within a few mK ...

Low temperature irreversibility induced by thermal cycles on two prototypical phase separated manganites [PDF]

, 2003
We have studied the effect of irreversibility induced by repeated thermal cycles on the electric transport and magnetization of polycrystalline samples of La0.5Ca0.5MnO3 and La0.325Pr0.3Ca0.375MnO3.
