A Hall Effect Reversal: The Unlikely Twist in Magnetic Sensing The discovery by Carnegie Mellon University researchers of an in plane anomalous Hall effect has sent shockwaves through the condensed matter physics community, challenging a century old assumption and opening up new possibilities for magnetic sensing.
This unexpected turn of events highlights the dynamic nature of scientific inquiry and underscores the importance of questioning established principles.
Since Edwin Hall's pioneering work in 1879, the conventional understanding of the Hall effect has been deeply ingrained in our collective psyche: a magnetic field deflecting moving charges to create a measurable voltage.
