Uranium ditelluride is an inorganic compound with the formula UTe₂. It was discovered to be a superconductor.¹ Due to the robustness of the superconducting state to magnetic fields, it has been suggested that it is an unconventional superconductor and possibly a spin-triplet superconductor.

Superconductivity

It has been suggested that the superconducting state in UTe₂ hosts spin-triplet pairs.² With recent crystal growth techniques a superconducting transition temperature of 2.10 K has been reached as of 2025.³

In scanning tunneling microscopy measurements, charge density waves (CDW)⁴ and pair density waves (PDW)⁵ have been reported, however later studies failed to detect these in the bulk of the material⁶⁷⁸, suggesting that they might be a surface phenomena.
