Electron beam irradiation into type-Ib diamond is known as a good method for the creation of high concentration negatively-charged nitrogen-vacancy (NV−) centers by which highly sensitive quantum sensors can be fabricated. In order to understand th

Silicon vacancies (Vsi) in silicon carbide (SiC) have attracted attention because they can be used for quantum sensors (F. Fuchs et al., Nat. Com. 6: 7578 (2015)). We aim to develop Vsi magnetic sensors operating at high temperatures because of its s
