90+ Claude Opus 5.5 agents find two room-temperature magnetic semiconductor candidates in 3 days
Dr_Singularity · x · 2026-10-06
- The Vals AI team ran 90+ Claude Opus 5.5 agents for 3 days and uncovered two room-temperature antiferromagnetic semiconductor candidates in simulation: newly designed YBaMnFeO₅ and KV[Cr(CN)₆], first synthesized in 1999.
- These materials could enable next-gen spintronic memory, combining semiconductor behavior, spin sorting, near-zero stray fields, and operation above room temperature; one stayed magnetically ordered up to 376 K (103°C) experimentally.
- Full calculations, code, and caveats are being shared openly.
