Abstract

Superconductivity was recently discovered in the clathrate hydride CeH9 with superconducting temperature (T c) of 57 K at pressures below 1 megabar. Here, the authors show that T c can be increased to 148 K in the substitutional alloy (La,Ce)H9, while maintaining a pressure below 1 megabar.
