This has been accomplished by monitoring the voltage-induced change of the longitudinal MOKE signal as a function of the applied magnetic field and applying an AC voltage across the interface. For the case where the spin polarization enters the VMOKE signal, a simple quantitative model is proposed. A distinct positive majority spin polarization has been found for Fe and Co, whereas Ni exh","authors_text":"Eberhard Goering, Gisela Sch\\\"utz, Michael Miller, Rene Nacke, Sven Ilse","cross_cats":["cond-mat.mtrl-sci"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"physics.app-ph","submitted_at":"2023-08-11T12:20:55Z","title":"Direct determination of the spin-polarization at buried interfaces using voltage dependent MOKE signals"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2308.06099","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":"sha256:501c900396aeb7c52b0e1c85eace5ec7a917e5c6fa69bdfbdac87c54475b7502","target":"record","created_at":"2026-07-05T07:44:43Z","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":"8e65d968904323cf82e0fc5e26a0f10abc41ed4600a892754e62263e599f2483","cross_cats_sorted":["cond-mat.mtrl-sci"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"physics.app-ph","submitted_at":"2023-08-11T12:20:55Z","title_canon_sha256":"06c95512d842f7ec7998a43789d376c112b58c709c061de398d56a3108b0ae26"},"schema_version":"1.0","source":{"id":"2308.06099","kind":"arxiv","version":2}},"canonical_sha256":"413749d8d08a0205ce86cd131d5fdf6c0d471779a20c9a0211120e45f63339fc","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"413749d8d08a0205ce86cd131d5fdf6c0d471779a20c9a0211120e45f63339fc","first_computed_at":"2026-07-05T07:44:43.618520Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T07:44:43.618520Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"hih6YLHxhElFnk1Y+ra+b63CD6NczPMLiVWJe55+LWBXyOSMYZYgDG6c33yrpOM+K4QaePU942x/CPorCwpJBA==","signature_status":"signed_v1","signed_at":"2026-07-05T07:44:43.618997Z","signed_message":"canonical_sha256_bytes"},"source_id":"2308.06099","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:501c900396aeb7c52b0e1c85eace5ec7a917e5c6fa69bdfbdac87c54475b7502","sha256:9a053b6da041283b94b7f425d2005f1c212e6b2444aa8653a287b96a6a77bbf8"],"state_sha256":"f6f6273eec9990a02f08d0a6b8ded5492129f6673f375c7be4a0152f20cc0486"}
