The experiment consisted of measurements of the dependence of the impedance of such systems with the temperature during heating (25 to 110 {\\deg}C) and cooling (110 to 25 {\\deg}C). The goal was to try to avoid the effect of humidity in the impedance spectrum. However, for the sample with x = 0.20, we get an anomalous response of the conductivity during the cooling process. To explain this result, we performed micro-structure characterization in this sample and in the samples with x = 0.80 an","authors_text":"Ant\\^onio G Souza Filho, Daniel Valim, Eder N Silva, Josue M Filho, Marco Aur\\'elio C de Santis, Oswaldo L Alves, Romildo J Ramos","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.mtrl-sci","submitted_at":"2019-08-01T19:41:25Z","title":"Ionic Conductivity Of Solid Oxides Hxag1-xtawo6.NH2O: Microstructural Aspects"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1908.00594","kind":"arxiv","version":1},"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":"sha256:9250aa7e9ddcb6b74baed85a5be467f98112a01d49b766a11d75026fd9a5bfc3","target":"record","created_at":"2026-07-04T23:51:07Z","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":"2941db4cb830ed4d02debfe4ae07144a4bc4beda59776a8c45d644264115abdf","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.mtrl-sci","submitted_at":"2019-08-01T19:41:25Z","title_canon_sha256":"ef487adbf9b4385dffb2f2e3f11ac29cebcb5d9f4a95ece06f546136502a3905"},"schema_version":"1.0","source":{"id":"1908.00594","kind":"arxiv","version":1}},"canonical_sha256":"8299474b56b1b7a227b165204bf68eada63a6abdc21bbd4ef17b30b62c223030","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"8299474b56b1b7a227b165204bf68eada63a6abdc21bbd4ef17b30b62c223030","first_computed_at":"2026-07-04T23:51:07.079941Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-04T23:51:07.079941Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"L6gulaoNWTt55Y8CZh8+o04ZKrLf1Rok1Dh+1eU+1WX4OYM+2IXdafU7G847fLjqMadEJW4QygKDpNrbkmPYDw==","signature_status":"signed_v1","signed_at":"2026-07-04T23:51:07.080427Z","signed_message":"canonical_sha256_bytes"},"source_id":"1908.00594","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:9250aa7e9ddcb6b74baed85a5be467f98112a01d49b766a11d75026fd9a5bfc3","sha256:0182d1b663456056c8eff86f4aaf96c17377757472f23dd481ad3bc5f9e122ae"],"state_sha256":"8ee9c695a5e507a3561bc398bc6e89919afc1e8bc12bbce2c0a7e34df40222bd"}
