arXiv:2510.03256v1 Announce Type: new
Abstract: We report experimental results indicating possible high-temperature superconductivity in graphite intercalation compounds synthesized with lithium-based alloys. Temperature-dependent measurements of magnetization, trapped magnetic flux, and electrical resistance reveal transitions with critical temperatures (Tc) in the range of 240-350 K at ambient pressure, depending on intercalation metals and conditions. The highest Tc values and largest high-Tc fractions (
