This replication by Huazhong University includes PPMS data, showing a strong signal of a diamagnetism transition at around 320K. It does not include a resistance measurement, however.
Think of this as a citation gold rush. You need to get on the band wagon early to become part of "the standard references" that everyone has to cite regardless of relevance. People will avoid making outlandish claims in order not to look stupid a year later in case things didn't work out -- no follow up work thus far has actually claimed to see superconductivity, just innuendos.
Not saying LK99 is or is not the wonder material, but right now it's more of a sociological experiment.
I wonder how many labs need to replicate the result before it is accepted as factual? This will be an interesting one to watch.
The video they included is weird. It looks like less than a milligram of material. And they didn't show... the conductivity...
I'm waiting until the Argonne national lab's results, as they've got the original sample from the Korean scientists. I expect that will be the decider for many people on whether this is something that's worth their attention
Edit: nvm I was wrong, they don't have the original sample
