Researchers have discovered a material, copper-substituted lead apatite, that may exhibit superconductivity at room temperature, as indicated by the possible Meissner effect observed in their experiment. The material shows diamagnetic dc magnetization under a magnetic field of 25 Oe and paramagnetism under 200 Oe. The study suggests that this material could have novel electromagnetic effects, even if it is not a true superconductor. Further research is needed to confirm the findings.
