Even after 145 years, the Hall effect remains relevant, playing a crucial role in various modern-day applications such as drones, proximity sensors, EV chargers, DC motors, hard drives, etc.
However, a new study from Pennsylvania State University (PSU) researchers proposes a new version of the Hall effect that doesn’t require a magnetic field to work. “In this work, we report the first observation of a room-temperature colossal nonreciprocal Hall effect,” Zhiqiang Mao, one of the study authors and a professor at PSU, said.
