Here, we report the observation of a large negative tunneling magneto-resistance (TMR) in the CoFeB/MgO/CoFeB system with an orthogonally-magnetized configuration. Through the thickness modulation of the MgO barrier, the negative TMR component can be enhanced up to 20% under a negative voltage bias. Moreover, the tunnel anisotropic magneto-resistance measurements unveil that the negative TMR component likely arises from the interfacial resonance states (IRS) in the min","authors_text":"Aitian Chen, Albert Lee, Bin Fang, Di Wu, Jianting Dong, Jia Zhang, Jiuming Liu, Puyang Huang, Xinqi Liu, Xi-Xiang Zhang, Xufeng Kou, Zhenghang Zhi","cross_cats":[],"headline":"","license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"physics.app-ph","submitted_at":"2023-07-27T12:27:20Z","title":"Interfacial Resonance States-Induced Negative Tunneling Magneto-resistance in Orthogonally-Magnetized CoFeB/MgO/CoFeB"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2307.14807","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":"sha256:9e65efdebec40be929599f4b1089ac0f527f575bfeffc07983908e9349c4019f","target":"record","created_at":"2026-07-05T06:35:18Z","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":"4b13be584f586b617d8c474b409d0483414e54c0f61e5fdf673e221412f63301","cross_cats_sorted":[],"license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"physics.app-ph","submitted_at":"2023-07-27T12:27:20Z","title_canon_sha256":"baf4730779a790296ab8c7dc7c6d8aaa5cdc80da386bbb24cf0275ef5214f994"},"schema_version":"1.0","source":{"id":"2307.14807","kind":"arxiv","version":1}},"canonical_sha256":"c292e8fdcb1ee8fac53e9426b9620f165433bc9de659c94ca63b224e4cd1ebed","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"c292e8fdcb1ee8fac53e9426b9620f165433bc9de659c94ca63b224e4cd1ebed","first_computed_at":"2026-07-05T06:35:18.161854Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T06:35:18.161854Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"yFYkYng0PMVCT3AeRSo8p6AjFwkIk+Ez9X41wr8P3sDRoYJiFqkbfr5RncvYJG1tL3W5Lh3JY9CzBwGPn7mvCg==","signature_status":"signed_v1","signed_at":"2026-07-05T06:35:18.162333Z","signed_message":"canonical_sha256_bytes"},"source_id":"2307.14807","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:9e65efdebec40be929599f4b1089ac0f527f575bfeffc07983908e9349c4019f","sha256:0fe02b3057a77112a7168f432fc86218b1752290f027e8f7ef7a4da9728fdef9"],"state_sha256":"9886dc95b888288b5cb2a62e2fe733d6babb9f69b853de1d73656c0e19315847"}
