The material's two magnetic phases, which differ in their orthorhombic and tetragonal lattice symmetries, share very similar strengths of magnetic interactions as seen from the high-energy excitations. At low energies, excitations polarized along the $c$ axis are suppressed in the tetragonal magnetic phase, in accordance with the associated reorientation of the ordered moments. Although excitations perpendicular to the $c$ axis are still prominent, only the we","authors_text":"Jianqing Guo, Kazuki Iida, Kazuya Kamazawa, Lei Chen, Li Yue, Tingting Han, Yan Zhang, Yuan Li","cross_cats":["cond-mat.str-el"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.supr-con","submitted_at":"2018-07-12T08:19:53Z","title":"Preferred magnetic excitations in Sr$_{1-x}$Na$_x$Fe$_2$As$_2$"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1807.04462","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:c7137c51388f4cc46ec52114696fdeb2becc9926ef9b76b96cf21ff3cef07e15","target":"record","created_at":"2026-05-17T23:56:47Z","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":"500d3981c66b2c3bbce1ba5843c3ac0120e0d54306901dbab9a8091b4e8c02d0","cross_cats_sorted":["cond-mat.str-el"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.supr-con","submitted_at":"2018-07-12T08:19:53Z","title_canon_sha256":"c76a321b693e0147a178e53844991498bc23a5c426fde7c0f5b8ddab22b77e9f"},"schema_version":"1.0","source":{"id":"1807.04462","kind":"arxiv","version":1}},"canonical_sha256":"5bf1c2e4ac54d75c84cdf2ed6764545832cf96122cab89fa70f9636f3c078696","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"5bf1c2e4ac54d75c84cdf2ed6764545832cf96122cab89fa70f9636f3c078696","first_computed_at":"2026-05-17T23:56:47.673490Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-17T23:56:47.673490Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"emlw7+Wz41yQvf+PX419mv1jqheADaE9NiNQureY33PCMvCkPLA0n3kayzecjvn2wr7lLjUWZSybcVKncENUBQ==","signature_status":"signed_v1","signed_at":"2026-05-17T23:56:47.673903Z","signed_message":"canonical_sha256_bytes"},"source_id":"1807.04462","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:c7137c51388f4cc46ec52114696fdeb2becc9926ef9b76b96cf21ff3cef07e15","sha256:7452bf0e4dbb73d386528cdde7fe0e9759976a3ec832f1cc69b2bf3550bcf5a0"],"state_sha256":"682c5041e4473f7adfd51bb9a9b232e97fa83971f500792fee29f7eaf85204e1"}
