Abstract
The authors investigate the normal transport of superconducting FeSe1-xSx across a nematic phase transition using high magnetic fields up to 69 T to establish the temperature and field-dependencies. They find that the low temperature transport and magnetotransport of the nematic electronic state of FeSe1-xSx is unique and it is significantly influenced by changes that occur in the electronic structure and scattering with the lattice and spin fluctuations across the nematic phase transition.
