'Magic-Angle' Graphene Discovered to Have a Very Rare Form of Superconductivity - ScienceAlert
'Magic angle' twisted trilayer graphene doesn't only have an impressively exotic name, it might be a particularly rare type of superconductor, according to new research – one that could be useful everywhere from medical equipment to quantum computers.
Scientists are finding that stacking single-atom layers of graphene on top of each other at slightly different angles can create new materials with exciting properties, which led to the recent discovery of magic-angle twisted trilayer graphene.Now, a new study from the same team shows that this material could be a "spin-triplet" superconductor – one that isn't affected by high magnetic fields – which potentially makes it even more useful.Through a series of experiments, the team was able to show that magic-angle twisted trilayer graphene continued to behave like a superconductor at magnetic fields in excess of 10 Tesla – three times higher than would be expected from a spin-singlet material.One area where spin-triplet superconductors could be helpful is in MRI scans: If these machines could operate under higher magnetic fields, they could produce much more detailed pictures.
