The X-ray diffraction pattern of the as-sintered samples is well indexed on the basis of tetragonal ZrCuSiAs-type structure. We characterized transport critical current density Jc of the SmFeAsO0.7F0.3 wires in increasing and subsequently decreasing fields, by a resistive four-probe method. A transport Jc as high as ~1300 A/cm^2 at 4.2 K and self field has been observed for the first time in Sm-1111 ","authors_text":"Chunlei Wang, Dongliang Wang, Lei Wang, Xianping Zhang, Yanpeng Qi, Yanwei Ma, Zhaoshun Gao, Zhiyu Zhang","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.supr-con","submitted_at":"2010-02-28T05:06:12Z","title":"Low-temperature synthesis of SmFeAsO0.7F0.3 wires with high transport critical current density"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1003.0153","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":"sha256:47b85ffdb6412dcb678c8fc5ff42153d33a72e219a923a2893a173f5945ebe82","target":"record","created_at":"2026-05-18T02:08:48Z","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":"795f4a1daef91359cd24675f8dc23482f427b366aa04911d1d7ade9e5aa45b6c","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.supr-con","submitted_at":"2010-02-28T05:06:12Z","title_canon_sha256":"73453c31f320a83401e7f9109176abbda1680280a709708d3a0c6d47c024bbaa"},"schema_version":"1.0","source":{"id":"1003.0153","kind":"arxiv","version":1}},"canonical_sha256":"9c46f4b2bede0b35169ffd30c596e1c0c714a1e86f340f7ea8c6a4ed97baaeb7","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"9c46f4b2bede0b35169ffd30c596e1c0c714a1e86f340f7ea8c6a4ed97baaeb7","first_computed_at":"2026-05-18T02:08:48.424285Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T02:08:48.424285Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"4rgDQ4x3YwWvRuoa84pnDg27WasjP3hfgGfNLu6JaE7KlTrjLhB4mAStwfZeQPCflotXwZHEDVQ0yclpAElbCw==","signature_status":"signed_v1","signed_at":"2026-05-18T02:08:48.425120Z","signed_message":"canonical_sha256_bytes"},"source_id":"1003.0153","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:47b85ffdb6412dcb678c8fc5ff42153d33a72e219a923a2893a173f5945ebe82","sha256:ab44eb4dc3ff1c4cfc29059b2185e5c252c8852638578d1dbe8810db1ebd2b15"],"state_sha256":"d4426b45061ddb3a60e1051ef063ef9b4880af48deb039397320e211f8e2a4f3"}
