90+ Opus 5.5 Agents Find Two Room-Temperature Magnetic Semiconductor Candidates in 3 Days

scaling01 · x · 2026-10-06

ValsAI reports that 90+ Opus 5.5 agents uncovered two room-temperature magnetic semiconductor candidates in simulations over just 3 days: YBaMnFeO₅ and KV[Cr(CN)₆]. These materials sort electrons by spin while their magnetism cancels—a decades-long research goal.

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.
