The RKKY interaction enhances significantly for the low levels of hole doping owing to the nearly valence flat band. Remarkably, for the hole-doped phosphorene, the highest RKKY interaction occurs when two impurities are located along the zigzag direction and it tends to a minimum value with changing the direction from the zigzag to the armchair direction. We show that the interaction is highly anisotropic and the magnetic ground-state of two magnetic adatoms can be tun","authors_text":"Fariborz Parhizgar, Moslem Zare, Reza Asgari","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.mes-hall","submitted_at":"2017-12-24T11:12:00Z","title":"Strongly anisotropic RKKY interaction in monolayer black phosphorus"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1712.08905","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":"sha256:5ec06352424c21cf08878637af931ef545ac1700f77c2303b0ffddf9452ad9f5","target":"record","created_at":"2026-05-18T00:22:39Z","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":"653dcad64697688e38f64a9f410166ca8e46a1ccd6fe5cd619756db3f9bd6783","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.mes-hall","submitted_at":"2017-12-24T11:12:00Z","title_canon_sha256":"0212e7af27a94b636840931afa7042f60b1707201f29d5951b276c7499cf733a"},"schema_version":"1.0","source":{"id":"1712.08905","kind":"arxiv","version":1}},"canonical_sha256":"48783d5111de32cbb1b8d91eba76f527e720ecb409290e6fc3b61bd79041286a","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"48783d5111de32cbb1b8d91eba76f527e720ecb409290e6fc3b61bd79041286a","first_computed_at":"2026-05-18T00:22:39.016908Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:22:39.016908Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"qpWRJtWNneQom6aC9RvuZWAZ4pHd/4KY6q+ijuIZmZzRGVYlvxpWK7KylhOrbj5prinDWeln7mDz9wOweRqpDQ==","signature_status":"signed_v1","signed_at":"2026-05-18T00:22:39.017258Z","signed_message":"canonical_sha256_bytes"},"source_id":"1712.08905","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:5ec06352424c21cf08878637af931ef545ac1700f77c2303b0ffddf9452ad9f5","sha256:1872010357d02d9032d8fc281b17ae505e5739f659f1a26427ba9098a60a5177"],"state_sha256":"da0bcd7440bdff5a2d55ec27f9e42d2d887902f0b4f2878095ab95acd0eb8a9d"}
