In-plane anomalous and third-harmonic Hall response in an easy-plane trigonal magnet
The episode discusses a paper detailing how tuning magnetic anisotropy in easy-plane trigonal magnets using selenium substitution can engineer an in-plane anomalous Hall effect and a third-harmonic Hall response. The hosts conclude that this work provides a blueprint for using material design to intentionally generate symmetry-protected nonlinear transport signatures, which is vital for developing controllable quantum devices.
