Physicists have managed to master magnetism - to create and manipulate magnetic fields- almost at will. Surprisingly, there is at least one property which until now has been elusive: how to 'switch off' the magnetic interaction of a magnetic material with existing magnetic fields without modifying them. Here we introduce the antimagnet, a design to conceal the magnetic response of a given volume from its exterior, without altering the external magnetic fields, somehow ana","authors_text":"Alvaro Sanchez, Carles Navau, Du-Xing Chen, Jordi Prat","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.supr-con","submitted_at":"2011-07-08T14:39:50Z","title":"Antimagnets: Controlling magnetic fields with superconductor-metamaterial hybrids"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1107.1647","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":"sha256:7814451178d1f27ee4d093b0e7aa23e5de95583ba2f4efeb9b5ab6402bc20c4e","target":"record","created_at":"2026-05-18T02:01:21Z","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":"f10d421d31043150da45657711413be87c7193158376ba92ca8674949b1d5f9f","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.supr-con","submitted_at":"2011-07-08T14:39:50Z","title_canon_sha256":"bb678c9aa511ba8697ad05f64acec6a4154ac5f1828548818021c931fe830777"},"schema_version":"1.0","source":{"id":"1107.1647","kind":"arxiv","version":1}},"canonical_sha256":"19b8359bdb20df535e38bf69260bee07118a0b797e58af720221f64c6adc3676","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"19b8359bdb20df535e38bf69260bee07118a0b797e58af720221f64c6adc3676","first_computed_at":"2026-05-18T02:01:21.280980Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T02:01:21.280980Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"fmENmwYTSEAqXTUA5DFqlUZtxDEjUWi+jeOo2U+ikPLZkeH7PGKwDwt0QdDIcdt81cdkD99/UubvTx25RNkqDQ==","signature_status":"signed_v1","signed_at":"2026-05-18T02:01:21.281736Z","signed_message":"canonical_sha256_bytes"},"source_id":"1107.1647","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:7814451178d1f27ee4d093b0e7aa23e5de95583ba2f4efeb9b5ab6402bc20c4e","sha256:36275da00c3dc68743b4a99fe1fda91079b0e01db15e246c8554cc3846b755f4"],"state_sha256":"b4671324895315f02b4c7bc711fa138bf47df7004b49f54397eb0d7d1cb71d74"}
