This isn't a particularly meaningful paper because they failed to produce any kind of partial levitation.

This one which finds substantial ferromagnetism and minimal diamagnetism is a far better reason to doubt that LK-99 is a superconductor:

Still very inconclusive because the synthesis is difficult and messy and nobody knows precisely what materials they're analyzing, but I've adjusted from cautious optimism to mostly resigned pessimism.
