The main researchers working on LK99-like room temperature and room pressure superconductors are in China and South Korea. There have been reports that the
With copper-substituted lead apatite below room temperature, Chinese researchers observe diamagnetic dc magnetization under magnetic field of 25 Oe with
LK99 is the material that South Korean researchers claimed in early 2023 was a room temperature superconductor. The South Korean Researcher will be reporting
A joint paper between Chinese and Japanese universities on LK-99 and published to the pre-print research server Arxiv seems to provide more smoke to the LK-99 superconductivity saga. The teams managed to replicate each others results in synthesizing copper-substituted lead apatite that showcased the Meissner effect (negating an externally applied magnetic field) due to superconductive hysteresis loops emerging at temperatures of 100 K (-173.15 ºC), 200 K (-73.15 ºC), and 250 K (-23.15 ºC) and possibly 300 K (26 ºC).
