Abstract:

These data are raw data as part of the manuscript: "Anomalous high-magnetic field electronic state of the nematic superconductors FeSe1−xSx" (arXiv:1904.02522) https://arxiv.org/abs/1904.02522. The manuscript will be published as an Article in Physical Review Research 2020. The magnetotransport data were collected using high magnetic fields with Helium 3 cryostats either in Nijmegen up to 38T , Tallahahassee up to 45T and pulsed fields close to 65T in Toulouse. The data were collected using lock-in amplifiers. The data here are part of the figures presented in the manuscript were detailed figure captions are provided.

Suppression of superconductivity and enhanced critical field anisotropy in thin flakes of FeSe

Abstract:

These data are part of the manuscript "Suppression of superconductivity and enhanced critical field anisotropy in thin flakes of FeSe" on https://arxiv.org/abs/1907.13174 which will appear in npj Quantum Materials 2020. The data are magnetotransport data on FeSe thin flakes. These data were mainly generated using a 16T PPMS in Oxford and the thin flakes were preparated at the University of Bath. The magnetotransport data were mainly funded by the Oxford Centre for Applied Superconductivity (CFAS) at Oxford University (www.cfas.ox.ac.uk).

Upper critical field in a stoichiometric iron-based superconductor, CaKFe4As4

Matthew Bristow, Amalia Coldea

Abstract:

These data are part of the manuscript (arXiv:2003.02888) entitled: "Competing pairing interactions responsible for the large upper critical field in a stoichiometric iron-based superconductor, CaKFe4As4". The data represent resistivity data collected at low temperatures and in magnetic fields up 16T using a superconducting magnet in Oxford as well as in pulsed fields up to 80T at the LNCMI in Toulouse, France. The measurements were performed between 2K and 300K either at constant temperature and varying the magnetic field or keeping the field constant and varying the temperature.
