Our experiments, focused on femtosecond laser-induced magnetization reversal, methodically vary the thickness of the copper (Cu) spacer layer. We identify a critical Cu thickness threshold at 2.32 nm. Above this threshold, a stable reversed magnetic domain is consistently generated upon exposure to a single laser pulse. Conversely, with a Cu spacer thinner than 2.32 nm, the observed magnetization reversal from parallel (P) to anti","authors_text":"Gregory Malinowski, Jon Gorchon, Julius Hohlfeld, Junta Igarashi, Michel Hehn, Stephane Mangin, Yann Le Guen","cross_cats":["cond-mat.mes-hall"],"headline":"","license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"cond-mat.mtrl-sci","submitted_at":"2023-11-21T17:59:13Z","title":"Influence of interlayer exchange coupling on ultrafast laser-induced magnetization reversal in ferromagnetic spin valves"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2311.12753","kind":"arxiv","version":2},"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":"sha256:1d791f412ee466b2f6634a5577f574bb866d0f1a32306cb694685714daa8b53d","target":"record","created_at":"2026-07-05T10:40:32Z","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":"64ef5914078cf7e42f21cef8944b0be74094f70af42b471c18d2df8763a1924b","cross_cats_sorted":["cond-mat.mes-hall"],"license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"cond-mat.mtrl-sci","submitted_at":"2023-11-21T17:59:13Z","title_canon_sha256":"719a4a463aa2ee9084dadc7c5340c33fc693048d75e06897709d79e9f37687dc"},"schema_version":"1.0","source":{"id":"2311.12753","kind":"arxiv","version":2}},"canonical_sha256":"348644086845b35ac09528d57347dbc69bf33131741b885b4052ea85168c4714","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"348644086845b35ac09528d57347dbc69bf33131741b885b4052ea85168c4714","first_computed_at":"2026-07-05T10:40:32.830558Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T10:40:32.830558Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"ILoCXOgYLtFxLMc7Ec1Qg9cjrojBAgKPWJ9wcTHrTm0o3lKZaSgNOQEBKLJ8Dh0gOLLbD3FXr2hgn9MtAvXLCA==","signature_status":"signed_v1","signed_at":"2026-07-05T10:40:32.830999Z","signed_message":"canonical_sha256_bytes"},"source_id":"2311.12753","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:1d791f412ee466b2f6634a5577f574bb866d0f1a32306cb694685714daa8b53d","sha256:249fac0cb86ecc7b7a3afcee06254189ba4ab99724d6ed9c5e3361523778c571"],"state_sha256":"ca2feb17e175dc69ae8f00680f714b58f2406bc974eb95d8dc5e04c69861cc3d"}
