These observations indicate intensified spin fluctuations in the gigahertz range. A phenomenological model of magnetic-noise-induced NV relaxation reproduces the temperature dependence of G1 by combining antiferromagnetic, ferromagnetic, and paramagnetic fluctuation channels, indicating that magnetic noise is strongest in the ferromagnetic regime.","weakest_assumption":"That the large changes in NV contrast, Rabi collapse, and T1 are caused primarily by magnetic fluctuations from the CrCl3 sample rather than other sources such as temperature-dependent instrumental effects, surface contamination, or non-magnetic noise channels."}},"verdict_id":"c6a56196-4ed0-4566-805a-47395bf52579"}}],"author_attestations":[],"timestamp_anchors":[],"storage_attestations":[],"citation_signatures":[],"replication_records":[],"corrections":[],"mirror_hints":[],"record_created":{"event_id":"sha256:3f64cad1c04fd10ef5cc46a195fd8c306848b36fec89cc3b828a2d06163e8b03","target":"record","created_at":"2026-07-02T00:18:29Z","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":"a7df4a6ee3a748d812e6aeca4dd8378b88b4a63637b29e67bc08f229cbcee54b","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.mes-hall","submitted_at":"2026-04-27T21:02:56Z","title_canon_sha256":"af0671229f66e0c404e8dc1cbf3cfb8c821efb93644686a3be3b74c735f7f2e6"},"schema_version":"1.0","source":{"id":"2604.25002","kind":"arxiv","version":2}},"canonical_sha256":"256ba3efcb12d3a91e9f0cff9ca87ef5e6de0cf3aca0c6e297638cd1255977b8","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"256ba3efcb12d3a91e9f0cff9ca87ef5e6de0cf3aca0c6e297638cd1255977b8","first_computed_at":"2026-07-02T00:18:29.355509Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-02T00:18:29.355509Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"HcvLGQKmwWgJ72iPsr5Bly1rswwyn684YSo+FebCKCaUlVu7ohAXhjVqjr4HI11OA4NpMEoX0EJmN34xQtp3AQ==","signature_status":"signed_v1","signed_at":"2026-07-02T00:18:29.356152Z","signed_message":"canonical_sha256_bytes"},"source_id":"2604.25002","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:40945753d6cfd3260408797aa348c0e5dc1e7f984e55bcb97d4ebe91173da9f2","sha256:3f64cad1c04fd10ef5cc46a195fd8c306848b36fec89cc3b828a2d06163e8b03","sha256:1eccbf9e61db9dfcdcc6d36ceb764eebaf921bef004b1bb1f2a8d896ed23071d"],"state_sha256":"53513bfc96feb8783f241fd205a98f277e55f05ecd8fa03b9754df1b229d5a58"},"bundle_signature":{"signature_status":"signed_v1","algorithm":"ed25519","key_id":"pith-v1-2026-05","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","signature_b64":"wZs2Q1vyAoOVj5pmh+qBkYPRm9Sc3k8CvrvxkbfKhcafqw95NzZzMYl1wHZUvustd7Gsv9fWZC98H9arIDkeCg==","signed_message":"bundle_sha256_bytes","signed_at":"2026-08-05T11:18:41.191160Z","bundle_sha256":"208cbf6613892f71ca68b3ad925bd58d9b6f475aef7bca790cd2111553721d8b"}}
