Evidence for Near Ambient Superconductivity in the Lu-N-H System

Nilesh P. Salke, Alexander C. Mark, Muhtar Ahart, Russell J. Hemley

Abstract

The recent report of superconductivity in nitrogen-doped lutetium hydride at near-ambient pressures and temperatures has attracted great attention but also continuing controversy. Several experimental groups have reported no observation of superconductivity at these conditions in Lu-N-H samples they have prepared. To address this issue, we have carried out a series of studies of phases in the Lu-N-H system using a variety of techniques. We report here electrical resistance measurements on a Lu-N-H sample that are in very good agreement with both previously reported Tc and its pressure dependence in the vicinity of room temperature for nitrogen-doped lutetium hydride.

    • The measurements were reproduced by a different team on samples provided by Dias: https://arxiv.org/abs/2306.06301

    • This the same discovery which was supposedly replicated by another team just last month: https://arxiv.org/abs/2306.06301 Of course, the researcher in question has already raised venture funding (~$16.5M) and filed for patents.
