Co-Author of LK-99 Room Temperature Superconductors Would Not Make Diamagnetism Mistake

by

Hyun-Tak Kim wrote a paper on diamagnetic shielding for high temperature superconductors in 2001. Hyun-Tak Kim is one of the six people who wrote the LK-99 room temperature superconductor paper. He is very familiar with diamagnetism. Hyun-Tak was brought in a few years ago when the Korean team knew they needed help to get it published in American science journals.

Diamagnets and Superconductors can levitate over other magnets. The top example is Diamagnet levitation and below is the Lk-99 levitation. Superconductors have the meissner effect levitation.

It is hugely important if the regular pressure room temperature superconducting work for the LK-99 material is confirmed.

  1. If LK-99 is a room-temperature superconductor, all this cheerleading is unnecessary. It will be replicated soon if true! The amount of hype being pushed may allow for Korean stock manipulation, but will have no effect on the final truth.

    The “levitation” does not look much like the Meissner effect: the chip is making contact with the surface, which can be simulated even without diamagnetism if a magnet is strong enough. Much about the process of how science is typically done is nonstandard here, and it makes me highly skeptical of the robustness of results.

    Of course we all want this to be true, but all the hype surrounding it—in particular, misinformation and the making of bold, highly exaggerated and unverified claims (it is not trivial to replicate and test tiny samples for superconductivity, so a “mistake” is something any researcher could make!)—is making the situation look fraudulent. This is not fair to the researchers.

    We must have patience and wait for replication and peer review. In the interim, none of us here know whether this is a room-temperature superconductor, including even the first authors (based on notable omissions in the two preprint papers).

    • It could still be error. This is more complicated than it appears.

      Patience: within about two weeks we should know for certain.

    I am quite skeptical too.

    However, even if there are no immediate practical applications this, if gets replicated, would be a huge win as it will lead to a theoretical foundation, which eventually might lead to common applications.

    Room temperature super conductors even if brittle will improve the efficiency of many devices. I can immediately think of quite a few

  4. Well I’m really hopeful this is real but given we’ve been burned before I remain sceptical.

    Also, the discovery is one thing, getting to practical commercial products is another matter. Just look at carbon nanotubes. We still don’t have widespread use
