Uranium ditelluride is an inorganic compound with the formula UTe2. It was discovered to be a superconductor. 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. With recent crystal growth techniques a superconducting transition temperature of 2.10 K has been reached as of 2025. In scanning tunneling microscopy measurements, charge density waves (CDW) and pair density waves (PDW) have been reported, however later studies failed to detect these in the bulk of the material, suggesting that they might be a surface phenomena.
