90+ Opus 5.5 agents uncover two room-temp magnetic semiconductor candidates in 3 days

ValsAI ran 90+ Opus 5.5 agents for 3 days in simulation and surfaced two room-temperature magnetic semiconductor candidates: YBaMnFeO₅ and KV[Cr(CN)₆]. These materials sort electrons by spin — a long-sought goal in spintronics.
Notably, KV[Cr(CN)₆] was synthesized back in 1999, meaning its predicted spin-sorting ability has been hiding in plain sight for 27 years.
Researcher @jazzloaf notes this isn't the first room-temp magnetic semiconductor system (EuO on Fe, (Fe,Ga)Sb, doped TMDs), but remains bullish on a more magnetic future of computing.
