X-ray diffraction experiments are performed at room temperature, 381 and 467 K up to 53 GPa, 30 GPa and 26 GPa respectively. The observation of the superstructure reflections in the X-ray patterns provides evidence that the crystal undergoes at all investigated temperatures a pressure-induced transition from cubic to the tetragonal I4/mcm phase, identical to the low-temperature phase.","authors_text":"Denis Machon, Jens Kreisel, Mael Guennou, Pierre Bouvier","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.mtrl-sci","submitted_at":"2009-10-05T10:08:56Z","title":"Pressure-temperature phase diagram of SrTiO3 up to 53 GPa"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"0910.0710","kind":"arxiv","version":3},"verdict":{"created_at":null,"id":null,"model_set":{},"one_line_summary":"","pipeline_version":null,"pith_extraction_headline":"","strongest_claim":"","weakest_assumption":""}},"verdict_id":null}}],"author_attestations":[],"timestamp_anchors":[],"storage_attestations":[],"citation_signatures":[],"replication_records":[],"corrections":[],"mirror_hints":[],"record_created":{"event_id":"sha256:f48f14209f5133930e8cd744bb2a3c896761cb60ed917301ee3995b35d8dcffb","target":"record","created_at":"2026-05-18T04:16:30Z","signer":{"key_id":"pith-v1-2026-05","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","signer_id":"pith.science","signer_type":"pith_registry"},"payload":{"attestation_state":"computed","canonical_record":{"metadata":{"abstract_canon_sha256":"1759b5010a6f47c5315b00cf13d62a68598ee1077221a8a1c5b44f83265a4f84","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.mtrl-sci","submitted_at":"2009-10-05T10:08:56Z","title_canon_sha256":"1b626a82b9594a440c6d882d3e8363f9a9e23b1fd7c2fe5ddf1cb8f6a69281fb"},"schema_version":"1.0","source":{"id":"0910.0710","kind":"arxiv","version":3}},"canonical_sha256":"519224e8d377ecfdb3a534ffc3c7eebf10a5b0498e5d2490e9b9eab314af7856","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"519224e8d377ecfdb3a534ffc3c7eebf10a5b0498e5d2490e9b9eab314af7856","first_computed_at":"2026-05-18T04:16:30.959458Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T04:16:30.959458Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"OFbdGJ4jdgOiwkOmauRyp6JUMhpYnoTwvF4cUizK231f/1o0Jz8Jn3/N7kYWKJt+5Uw89KBHXHQYJ4MIrYQ2Cw==","signature_status":"signed_v1","signed_at":"2026-05-18T04:16:30.959821Z","signed_message":"canonical_sha256_bytes"},"source_id":"0910.0710","source_kind":"arxiv","source_version":3}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:f48f14209f5133930e8cd744bb2a3c896761cb60ed917301ee3995b35d8dcffb","sha256:64f06d1e4ecbb2dcfb9a5e57e22adee21e787141d10182a3db1e98f23a2792a4"],"state_sha256":"01059c1f4f1e487a2d43b1babc051c2bdbc1bb100aea3eb4fa827c7b3bebc73b"}
