Uranium ditelluride
Chemical compound
From Wikipedia, the free encyclopedia
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 material[6][7][8], suggesting that they might be a surface phenomena.
