Impact of growth parameters and treatment of single crystals on the superconductivity in UTe<sub>2</sub>

ORAL

Abstract

Recently discovered heavy-fermion superconductivity in UTe2 with the transition temperature Tc~1.6 K attracts much attention. The superconducting state of UTe2 closely resembles that of ferromagnetic superconductors. However, the normal state of UTe2 is, uniquely, paramagnetic. UTe2 is hosting two independent field-induced superconducting phases with a reentrant behavior at 45 T and persisting up to 65 T. Most likely spin-triplet superconductivity is realized in UTe2. Variation of Tc and the order parameter, single or multiple components, has been reported, which is likely to depend on the quality of the single crystals. We would like to discuss the impact of growth techniques and treatments of single crystals on the superconducting state in UTe2 .
