The superconducting transition temperature 
in the spin-triplet superconductor UTe increases from the initial reported value of 1.6 K to 2.0 K as the newly reported one improving the growth condition. We have developed a growth method for the superconductor UTe that is different from the usual chemical vapor phase transport method. As a result, we have succeeded in growing high-purity UTe crystals at 
=2.1 K and confirmed that the residual specific heat below is very low and the residual ratio of electrical resistance is very large. We report the optimization of the newly developed method for UTe.

High-quality UTe single crystals were grown using a molten salt flux method with the highest reported superconducting (SC) transition temperature. The crystals had a small residual electronic contribution in specific heat and a large residual resistivity ratio. The SC phase diagram of UTe was studied, revealing contrasting field-angular dependence of low and high-field SC phases. An intermediate SC state was also found. The high-field SC phase appeared consistently at about 15 T, while crystal quality increased the upper critical field of the low-field superconducting phase. The MSF method facilitated the observation of quantum oscillations and progress in Fermi surface research for this spin-triplet superconductor.

In this talk, I will briefly introduce the growth of high-purity single crystals of the novel superconductor UTe using the molten salt flux method. Additionally, we will present the superconducting phase diagram when applying a magnetic field along the crystal's 
-axis, corresponding to the magnetic hard axis, using a high-purity single crystal with a superconducting transition temperature 
= 2.1 K.
