The usual difficulties associated with the production of robustly-insulating ferromagnets are circumvented by incorporating the magnetism through {\\it ferri-}magnetic behavior. We show that the the ordered perovskite \\BFCO will have a polarization of $\\sim$80 $\\mu$C/cm$^2$, a piezoelectric coefficient of 283 $\\mu$C/cm$^{2}$, and a magnetization of $\\sim$160 emu/cm$^3$ (2 $\\mu_B$ per formula unit), far exceeding the properties of any know"},"claims":{"count":0,"items":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"cond-mat/0410268","kind":"arxiv","version":1},"verdict":{"id":null,"model_set":{},"created_at":null,"strongest_claim":"","one_line_summary":"","pipeline_version":null,"weakest_assumption":"","pith_extraction_headline":""},"references":{"count":0,"sample":[],"resolved_work":0,"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57","internal_anchors":0},"formal_canon":{"evidence_count":0,"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"author_claims":{"count":0,"strong_count":0,"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"builder_version":"pith-number-builder-2026-05-17-v1"}
