We can increase and reduce the value of the giant magnetoresistance by tuning the spin-polarized current, which is controlled by the magnetization configurations. The property is intuitively understood by the non-equilibrium spin-polarized current, which plays the role of an effective electrochemical potential on the surface of the TI.","authors_text":"Katsuhisa Taguchi, Takehito Yokoyama, Yukio Tanaka","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.mes-hall","submitted_at":"2013-09-17T06:34:48Z","title":"Giant magnetoresistance in the junction of two ferromagnets on the surface of diffusive topological insulators"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1309.4195","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":"sha256:44a9b572ff2fcb1d348d06798625192ebe7dcbfee96c2fc96a72fb808df8dd44","target":"record","created_at":"2026-05-18T01:47:36Z","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":"fd260bfd551557a7bad90fbfedc72b20c2742fbda9956b1965fb5fbe8d68c4bf","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.mes-hall","submitted_at":"2013-09-17T06:34:48Z","title_canon_sha256":"00dbbd7a93e451d93715ad05f0aa46bf51a1a26b3066729b035797185a09f92b"},"schema_version":"1.0","source":{"id":"1309.4195","kind":"arxiv","version":1}},"canonical_sha256":"7bb3cb113500f42001a25aea6102c4cda9383ba1bf7e277b574fddc9dc143e51","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"7bb3cb113500f42001a25aea6102c4cda9383ba1bf7e277b574fddc9dc143e51","first_computed_at":"2026-05-18T01:47:36.844007Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T01:47:36.844007Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"xQIF3ikT+/twTdaeVrvL0aiB/gsnE3IsLYbUCKvT9b9B9xXZW1Le9J/HCq6WdJWHeF+uaRskTrfIYol6tWIMAA==","signature_status":"signed_v1","signed_at":"2026-05-18T01:47:36.844713Z","signed_message":"canonical_sha256_bytes"},"source_id":"1309.4195","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:44a9b572ff2fcb1d348d06798625192ebe7dcbfee96c2fc96a72fb808df8dd44","sha256:5b8aef9731c8a718ac1d6e800e0d219278c2771e78303bb99da88c458a1088e3"],"state_sha256":"bc91476438dfb6829c1fa6116e55e4376a543c014cc44cd92458953c365d7748"}
