A recent study demonstrated near-ambient superconductivity in nitrogen-doped lutetium hydride 1 . This stimulated a worldwide interest in exploring room-temperature superconductivity at low pressures. Here, by using a high-pressure and high-temperature synthesis technique, we have obtained nitrogen-...
