Mn in high-spin S = 5/2, Mn$^2$$^+$ configuration, was detected regardless of the conductivity type of the host material. This means that Mn$^2$$^+$(d$^5$) energy level is located within the valence band, and Mn$^1$$^+$(d$^6$) energy level is outside the energy gap of Bi$_2$Se$_3$. The electron paramagnetic resonance spectrum of Mn$^2$$^+$ in Bi$_2$Se$_3$ is characterized by the isotropic g-factor |g| = 1.91 and large axial parameter D = -4.20 GHz x h"},"claims":{"count":0,"items":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1412.2012","kind":"arxiv","version":1},"verdict":{"id":null,"model_set":{},"created_at":null,"strongest_claim":"","one_line_summary":"","pipeline_version":null,"weakest_assumption":"","pith_extraction_headline":""},"references":{"count":0,"sample":[],"resolved_work":0,"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57","internal_anchors":0},"formal_canon":{"evidence_count":0,"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"author_claims":{"count":0,"strong_count":0,"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"builder_version":"pith-number-builder-2026-05-17-v1"}
