FERMI-SURFACE INSTABILITIES IN THE HEAVY-FERMION SUPERCONDUCTOR UTe2
Alexandre Pourret, CEA Grenoble and Gabriel Seyfarth, LNCMI-Grenoble. The recently discovered heavy-fermion superconductor UTe2 with superconducting transition temperature of 1.6 K is one of the rare examples of a heavy-fermion material with superconductivity appearing above 1 K. In contrast to the ferromagnetic heavy-fermion superconductors UCoGe and URhGe, UTe2 is [...]
