The reduction process leads to the formation of a 7-nm thick EuO smooth layer, without noticeable structural changes in the underlying chemical vapor deposited (CVD) graphene. The obtained EuO films exhibit ferromagnetism, with a Curie temperature that decreases with the initially deposited Eu2O3 layer thickness. By adjusting the thickness of the Eu2O3 layer below 7 nm, we promote the formation of EuO at the very graphene in","authors_text":"Aditi Raman Moghe, Corinne Bouillet, David Halley, Jean Francois Dayen, Jerome Robert, Raul Arenal, Satakshi Pandey, Simon Hettler, Stephane Berciaud","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.mtrl-sci","submitted_at":"2023-09-02T10:12:05Z","title":"Room-Temperature Anomalous Hall Effect in Graphene in Interfacial Magnetic Proximity with EuO Grown by Topotactic Reduction"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2309.00892","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":"sha256:2d48c77a630f038b1f26b8cf391040ee89d51dbdda676ecaee2f159a43cfadc3","target":"record","created_at":"2026-07-05T06:47:29Z","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":"4f145e898ae766cd6684d050ee4cc411ce1845d3f3b157c1bd876f96ab8c893e","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.mtrl-sci","submitted_at":"2023-09-02T10:12:05Z","title_canon_sha256":"706fa77e763d75b1fdfe486cba354055bcad5b9f2ae691d845b057d0cd0f7eab"},"schema_version":"1.0","source":{"id":"2309.00892","kind":"arxiv","version":1}},"canonical_sha256":"57d57fea0153cd6fa65d06bf2622b8b4ea780b7f72293a85ce51b29579d13d09","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"57d57fea0153cd6fa65d06bf2622b8b4ea780b7f72293a85ce51b29579d13d09","first_computed_at":"2026-07-05T06:47:29.325708Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T06:47:29.325708Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"dnfyQ+DFfzT4NOMnIf13Ai+yc0BXOK1eSwEt6ZpvjgOOijOAteSx07EnMQnHB8dkEA5l0wICpb6WDQ0kXczqDw==","signature_status":"signed_v1","signed_at":"2026-07-05T06:47:29.326193Z","signed_message":"canonical_sha256_bytes"},"source_id":"2309.00892","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:2d48c77a630f038b1f26b8cf391040ee89d51dbdda676ecaee2f159a43cfadc3","sha256:ec50a140dcb0defd1ac7da6311bbe6a020c9dd09c949ea08df24589dda40c3ad"],"state_sha256":"e8596dd68e4ac5f683c5c0bf1b62c478a6eededde73bbf822815cdf3cc1c3cdb"}
