Abstract
Muonium (Mu) centers formed upon implantation of 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, and BaTiOH oxyhydride.
