Carnegie Mellon Researchers Challenge Long-Standing Hall Effect Theory

A team at Carnegie Mellon University has observed an unexpected variant of the Hall effect, contradicting the century-old belief that this electrical phenomenon requires a perpendicular magnetic field. The discovery could reshape fundamental understanding of electron behavior in materials.

EXPANDED:

The Hall effect has historically been defined by the necessity of a perpendicular magnetic field to deflect moving charge carriers. A research team at Carnegie Mellon University has now documented a deviation from this foundational rule, observing an unexpected variant that operates without
