Superconductivity is strongly enhanced in the metastable $\\mathrm{\\beta}$-Ga with a critical temperature $T_\\mathrm{c}= 6.04(5)\\,\\mathrm{K}$, while stable $\\mathrm{\\alpha}$-Ga has a much lower $T_\\mathrm{c}<1.2\\,\\mathrm{K}$. Here we use a membrane-based nanocalorimeter to initiate the transition from $\\mathrm{\\alpha}$-Ga to $\\mathrm{\\beta}$-Ga on demand, as well as study the specific heat of the two phases on one and the same sample. The in-situ transformation is initiated by bringing the temperature to about $10\\,\\mathrm{K}$ above the melting t"},"claims":{"count":0,"items":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1803.06743","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"}
