A groundbreaking discovery has emerged in the world of superconductors, reshaping our understanding of the previously dismissed LK-99 material. A team of researchers from various prestigious institutions, including the South China University of Technology, Central South University, and University of Electronic Science and Technology of China, has observed a significant low-field microwave absorption (LFMA) hysteresis effect in copper-substituted lead apatite samples. This observation suggests a transition between the superconducting Meissner phase and vortex glass, hinting at the potential for room-temperature superconductivity.
Unveiling the Superconducting Phase
The team’s research paper, titled ‘Strange memory effect of low-field microwave absorption in copper-substituted lead apatite,’ has been made publicly available on the preprint website arXiv. According to Professor Yao Yao from the South China University of Technology, the study provides clear evidence of a superconducting phase, a significant step in the pursuit of room-temperature superconductivity. However, the transition temperature of the material currently stands at approximately 250K (-23.15C).\
