论文摘要
长期以来一直研究了固体中的$μ^+$在植入$μ^+$后形成的Muonium（MU）中心已被研究为一种实验可访问的分离氢杂质的模型。在氧气空缺中形成的水合体中心的最新发现激发了人们对H $^ - $和相应的Mu $^ - $ $ $^ - 氧化物中心的新兴趣。但是，两个磁性中心Mu $^+$和MU $^ - $很难在光谱上分离。 In this review article, we summarize established and developing methodologies for identifying Mu$^-$ centers in solids, and review recent Mu studies on said centers supposedly formed in mayenite, oxygen-deficient SrTiO$_{3-x}$, and BaTiO$_{3-x}$H$_x$ oxyhydride.
Muonium (Mu) centers formed upon implantation of $μ^+$ in a solid have long been investigated as an experimentally accessible model of isolated hydrogen impurities. Recent discoveries of hydridic centers formed at oxygen vacancies have stimulated a renewed interest in H$^-$ and corresponding Mu$^-$ centers in oxides. However, the two diamagnetic centers, Mu$^+$ and Mu$^-$, are difficult to separate spectroscopically. In this review article, we summarize established and developing methodologies for identifying Mu$^-$ centers in solids, and review recent Mu studies on said centers supposedly formed in mayenite, oxygen-deficient SrTiO$_{3-x}$, and BaTiO$_{3-x}$H$_x$ oxyhydride.
