Título: "Reentrant superconductivity and multiple superconducting phases in UTe2"

Dai Aoki
(IMR, Tohoku University, CEA-Grenoble)

Resumo:

We present our recent results on the novel spin-triplet superconductor UTe2, which might be at the verge of the ferromagnetic order. The huge upper critical field exceeding the Pauli limit is suggestive of the spin-triplet state. For the field along the b-axis, the field reentrant superconductivity is observed up to Hm~35T, at which the first order metamagnetic transition occurs. The field reentrant superconductivity in UTe2 is similar to those observed in ferromagnetic superconductors, namely URhGe and UCoGe. Applying the pressure in UTe2, the superconducting transition temperature splits and the multiple superconducting phase is detected as a thermodynamic response. We overview the results on UTe2 compared to ferromagnetic superconductors, and present our perspective.
