Successful room temperature ambient-pressure magnetic levitation of LK-99
Summary: Researchers have successfully synthesized LK-99 crystals, exhibiting room temperature ambient-pressure magnetic levitation. This verifies previous findings on atmospheric superconductivity in modified lead apatite crystals with a superconducting transition temperature above 400 K. The development brings non-contact superconducting magnetic levitation closer to realization.

Some remarks on possible superconductivity of composition Pb9CuP6O25
Summary: A study discusses the potential superconductivity of a material called LK-99, a modified-lead apatite crystal structure with the composition Pb$_{10-x}$Cu$_x$(PO$_4$)$_6$O ($0.9<x<1.1$). LK-99 has been reported to be an above-room-temperature superconductor at ambient pressure, but its reproducibility remains uncertain. The authors provide remarks that may aid in successful reproduction of the original results.
