No he doesn’t?
Don’t get me wrong there are many places where the paper can be wrong (eg fig 1 or their magnetism exceptionally looking more similar to diamagnetism than superconductivity) but you are mixing him up with Ranga Dias who has had a history of data fabrication.
Dias has nothing to do with this paper though.
The guy behind this paper has the exact same issues as Schon. Plagiarism in his PhD thesis, faked data, retracted papers, etc.
Got a source? When I first read about this people were cautiously optimistic partly because the head researcher was well-respected.
