Search for room-temperature magnetic semiconductor candidates

A Claude Opus 5.5 agent team screened Luttinger-compensated magnets and surfaced two predicted room-temperature magnetic semiconductor candidates.

What they did
A team of Claude Opus 5.5 agents worked with the author to hunt for Luttinger-compensated magnets, a class of antiferromagnets with no overall magnetization but still spin-ordered electrons. They tested candidates with density functional theory at two levels, PBE+U and HSE06. The agents then proposed a new compound, YBaMnFeO₅, and also pulled up KV[Cr(CN)₆], a material first reported in 1999.
How it went
Both compounds were predicted to be semiconductors with spin energy scales well above room-temperature thermal energy. YBaMnFeO₅ is likely to lose its magnetic order at the temperatures needed to make it, and KV[Cr(CN)₆] still has no measured band gap or spin-ordering data. The two calculation methods also disagreed about how water in the sample changes its behavior.
Tips
These results apply to ideal crystal models, so they should be treated as starting points rather than final proof. The next practical step is to remake KV[Cr(CN)₆] and measure it directly.

Try it yourself with Manus

Help me search for candidate room-temperature magnetic semiconductors in [material family or application]. Look through recent papers and open materials databases, then shortlist two candidates with any reported magnetic ordering temperature, band gap, and the evidence behind each claim. For each one, separate what is computed from what is experimentally measured, and stop to ask for my approval before you draft, submit, send, or otherwise finalize anything.
