摘要

本文将首先简要回顾在室温超导(RTS)出现之前,高温超导(HTS)领域取得的令人瞩目的进展。伴随着上个世纪超导科学与技术的进步,一个关于新发现的搜索、开发甚至鉴定的坚实实验框架已经建立起来。所有这些都可以作为 RTS 研究起步阶段的宝贵参考。本着这种精神,我们将对稀土氢化物 RTS 的现状进行评论,并介绍我们对 Lu-N-H 和 LK-99 的初步否定结果,这两种材料是近几个月来在寻找 RTS 的过程中研究得最多的材料,尽管否定的报告比肯定的多。

From high-temperature superconductivity to room-temperature superconductivity: From ambient to high pressure; from very high pressure to ambient again!?
This article will first briefly review the impressive advancements made in high-temperature superconductivity (HTS) before the arrival of room-temperature superconductivity (RTS). Accompanying the advancements made in superconductivity science and technology over the last century, a solid experimental framework concerning the search, development, and even authentication of new discoveries has been established. All these can serve as valuable references in the infancy of RTS research. In this spirit, we will comment on the current status of rare-earth hydride RTS and present our preliminary negative results on Lu-N-H and LK-99, the two most studied materials in the search for RTS in the last few months, although several more reports of negation than affirmation have appeared.
