Room Temperature Superconductor Team Video Evidence of Levitation and Zero Resistance Readings

by

Kim Hyun-tak (lead original south korean researcher) has a confident email to a colleague.

We [Original Korean Superconducting Researchers] designate March 4, 2024 as The Day of Room Temperature Superconductor (TDRTS) and researchers celebrate the day with delicious food. This is because it is the day when room-temperature superconductivity, such as magnetic levitation and zero resistance, is proven at the conference.

The talk was scheduled for a few minutes ago. Waiting to hear reports as it was NOT streamed live. Sinéad Griffin is one of the Berkeley National Lab scientists who worked on simulations of LK99.

The original team of South Korean LK99 Room Temperature and atmospheric pressure superconductors researchers will have a short 12 minute presentation at the American Physical Society conference. The new material is PCPOSOS which is LK99 with some sulfur in the chemistry.

We synthesized materials, Pb10-xCux(P(O1-ySy)4)6O1-zSz (PCPOSOS), called PCPOSOS, which exhibit superconducting behavior at room temperature and atmospheric pressure. These materials displayed characteristics of a superconductor, including zero resistance, the Meissner effect, and partial levitation when placed on a magnet (arXiv: 2307.12037). The partial levitation is caused by an inhomogeneity in the magnetic field of the magnet and occurred within the range of critical magnetic fields, Hc1 and Hc2. That is, the magnetic field of the magnet increased with going from center to the edge of magnet. The magnet had approximately 2000G at the center and approximately 3,000G at its edge. The levitation occurred near center. This indicates the center of the magnet is close to Hc1. It disappeared between center and the edge near Hc2, with Hc1 being much smaller than Hc2, because the magnetic moment at Hc2 is much smaller than that at Hc1. When the magnet is slightly moved, the levitation returns to its original position. This phenomenon is analyzed as flux pinning, which is typical of a type-II superconductor. Moreover, the quantum-locking phenomenon, characteristic of a Type-I superconductor, may appear. However, we interpret PCPOSOS as a Type-II superconductor. We will show two videos of levitations and two videos of magnets.

  2. “room-temperature superconductivity, such as magnetic levitation and zero resistance, is proven at the conference. ”

    I have seen videos and lots of ‘witnesses’ of Big Foot encounters, BUT not one noncontroversial piece of physical evidence.

    Until they have a physical sample that has been verified by SEVERAL independent respected laboratories… LK99 is a scam.

    Remember ‘cold fusion’? It had highly respected professors claim it existed, and many other claimed theoretically it was possible, BUT no verifiable experiment by several independent respected laboratories was ever made.

  3. How did the sulfur get in there? I recall that Iris Alexandra of Moscow was somewhat (reluctantly?) admitting that she might have let sulfur in as an impurity in the materials she was using in her alternative quicker synthesis.

    How was the doping level of Cu controlled? Has the bulk-sample synthesis procedure been modified to reflect this need? If so, what is it?

    • I sympathize with this view.

      I might describe my own view as pessimistically hopeful. If it turns out to be what they are claiming it is it will only deliver a few of the wish list items for a room temperature superconductor. Great for computers, lousy for fun magnets, if I understand correctly.

      But if (I say “if”) it delivers that much it could be promising for new materials research.

      I think there is a chance there is some substance behind it.

    • Someone claimed that MADA-9 made by the Taliban could do the hovering? on a curvy mountainous track such as in Afghanistan without getting offtrack a long time ago.
