prediction of gigantic anomalous Nernst effect in ferromagnetic monolayer transition metal trihalides.

The anomalous Hall conductivity of all transition metal trihalides was explored using first-principles calculations. Employing the Fukui-Hatsugai-Suzuki method, we found that ferromagnetic monolayersBr(= Pd, Pt) possessed the quantized anomalous Hall conductivity (QAHC) with and without carrier doping. Due to unique QAHC, their transverse thermoelectric properties ofBr(= Pd, Pt) were investigated.
