Calorimetric evidence of nodal gaps in the nematic superconductor FeSe
Calorimetric evidence of nodal gaps in the nematic superconductor FeSe
Superconductivity in FeSe has recently attracted a great deal of attention because it emerges out of an electronic nematic state of elusive character. Here we study both the electronic normal state and the superconducting gap structure using heat-capacity measurements on high-quality single crystals. The specific-heat curve, from 0.4 K to …
