On 2023-08-01, we have what appears to be the first report of an apparent replication of the LK-99 room temperature superconductivity results. This was posted on bilibili.com by two researchers at the School of Materials Science and Technology of Huazhong University of Science and Technology in China, which shows partial levitation of a flake of LK-99 they report having made. The video cannot be embedded here but may be viewed at the following links:
- LK-99验证 (Original Chinese)
- LK-99 Verification (English translation by Google Translate)
- Observing the magnetic reaction of a material under a magnet using a microscope (Translation of Chinese narration to English by Targum.video)
The description of the video, translated to English by Google Translate, is:
Under the guidance of Professor Chang Haixin, postdoctoral Wu Hao and doctoral student Yang Li of the School of Materials Science and Technology of Huazhong University of Science and Technology successfully verified and synthesized the LK-99 crystal that can be magnetically levitated for the first time. Larger, it is expected to realize the real non-contact superconducting magnetic levitation.
A follow-up video, also translated by Targum.video, “Testing the sample with a magnet” purports to show testing the sample with a magnet to demonstrate it’s not ferromagnetic. I cannot see the sample in the portrait mode blur-o-vision video posted.
Here is Andrew Cote’s analysis of the first video. The original tweet included an embed of the video above which I have elided because Twitter videos cannot be embedded here.
