In case you haven't already seen it. This lot claim to have made a superconductor "LK-99" with Tc > 100C.
(you have to wonder what happened to samples 1 thru 98)
Seems a bit unlikely to me. The odd science page in newspapers has
picked up on it but the story is mangled.
I found this on arXiv but it is a dog's dinner of a paper.
Can anyone remember enough TCM to make sense of it?
https://arxiv.org/abs/2307.12037
The recipe sounds simple enough (if rather odd) to try and replicate.
Any thoughts or clear refutations of their claims?
If it is a 1D superconductor along a preferred crystal axis then it may
have more interest as a tool for tormenting the BCS model than as a real
world material.
Whatever "superconducting" properties it has seem to revert to being
metallic with currents as low as 250mA.
Seems very odd to me that if it is genuine it isn't being announced on
the front page of Nature or a major Physics journal.
Thanks for any enlightenment.
