The results of our study indicate that interfacial Fe atoms in the Fe films have a low-dimensional nature, which causes the following two effects: (i) The diagonal component $\\sigma_{xx}$ of the optical conductivity decreases dramatically because the hopping integral for electrons between Fe atoms is suppressed by the low dimensionality. (ii) The off-diagonal component $\\sigma_{xy}$ of the optical conductivity does not change at low photon energies, but it is enhanced","authors_text":"Bo Gu, Saburo Takahashi, Sadamichi Maekawa","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.mtrl-sci","submitted_at":"2017-10-27T04:22:17Z","title":"Enhanced Magneto-optical Kerr Effect at Fe/Insulator Interfaces"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1710.09986","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:a12a9604186c7ba284a323bb6a0b1f85aa1c7a8cec2ba284a453601d5e26718f","target":"record","created_at":"2026-05-18T00:27:42Z","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":"b4d57a0b8090023e5bfc14f1161f2bed3f779fe81294301424c471d5b8e0be10","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.mtrl-sci","submitted_at":"2017-10-27T04:22:17Z","title_canon_sha256":"f4cf95e3ec5ff6c85d0ee2716befce660bd937b0e28fc29042ff3169d4ddcc7d"},"schema_version":"1.0","source":{"id":"1710.09986","kind":"arxiv","version":1}},"canonical_sha256":"684136756a4cebb242e7ab32e50b563cac24dea83624cfb770463c5d6dea2b58","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"684136756a4cebb242e7ab32e50b563cac24dea83624cfb770463c5d6dea2b58","first_computed_at":"2026-05-18T00:27:42.179076Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:27:42.179076Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"82qt7spfBGBSojbwXbZ7/UWyWEFWo4gwyyGCNwW/p+KtQ1o1kyKaU24UNaxy1GowGXJLX0PqIwD1VpmLBh8lBw==","signature_status":"signed_v1","signed_at":"2026-05-18T00:27:42.179636Z","signed_message":"canonical_sha256_bytes"},"source_id":"1710.09986","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:a12a9604186c7ba284a323bb6a0b1f85aa1c7a8cec2ba284a453601d5e26718f","sha256:5fa0bd8093c499909d7c1d1a8c58318cde928ede63f7dd6ccf066b9bcaebb959"],"state_sha256":"40280ce02bb607bece61659e517d5fab44e04c2116e7ee33471d299aad5b1135"}
