Here, we explore the previously uncharted Be Ag(II) F chemical space using global structure prediction algorithms combined with first principles calculations. Focusing on the AgBeF4 stoichiometry, we identify the five lowest enthalpy polymorphs crystallizing in the C2, P minus 1, and P 21/c space groups. All polymorphs show an antiferromagnetic ground state, with AgBeF4_4 and AgBeF4_5 exhibiting unprecedented strong superexchange","authors_text":"Katarzyna Kuder, Wojciech Grochala","cross_cats":["cond-mat.mtrl-sci","cond-mat.str-el"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.supr-con","submitted_at":"2026-07-09T11:41:56Z","title":"Theoretical exploration of Be Ag(II) F phases and their magnetic properties using learning algorithms"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2607.08372","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":"sha256:103c629ddaaf306ccb68599b0576af839c29d63e7c3f7ae532f24c35fd2a3d1a","target":"record","created_at":"2026-07-10T01:19:48Z","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":"442848b096060d2710866df2c1233c19f420cff4b60f94269c27d6211f2a17c4","cross_cats_sorted":["cond-mat.mtrl-sci","cond-mat.str-el"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.supr-con","submitted_at":"2026-07-09T11:41:56Z","title_canon_sha256":"69c00b2c55650ad69b6b8b1d3930df8f4157e9592e8aaa497349e5c6dc1159bc"},"schema_version":"1.0","source":{"id":"2607.08372","kind":"arxiv","version":1}},"canonical_sha256":"9bc34503a96ae543d43ab696bbed6cb3996522df421158618e6f4c247076bb43","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"9bc34503a96ae543d43ab696bbed6cb3996522df421158618e6f4c247076bb43","first_computed_at":"2026-07-10T01:19:48.366093Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-10T01:19:48.366093Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"Fc62W8vhPsv5Golr/03fRhdLStvtJx74ftihj2l8UBBXWxa1SQM3fjEbe7BQXqOaHrH+U6nlIdvGMc8rfqQTAw==","signature_status":"signed_v1","signed_at":"2026-07-10T01:19:48.366513Z","signed_message":"canonical_sha256_bytes"},"source_id":"2607.08372","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:103c629ddaaf306ccb68599b0576af839c29d63e7c3f7ae532f24c35fd2a3d1a","sha256:0716d08d2ac2c03882842fa8ffbfad67b5458c5d78bec9a5322e9d6e8dd69d98"],"state_sha256":"46dc6891e0b38372c3340b4a7585f12d24fe952e72ed540bb44be1997b2d2a7e"}
