In 1879, Edwin Hall discovered an electrical effect thought to need a perpendicular magnetic field; 147 years later, scientists have shown it can work with the field in-plane
An atomic force microscopy scan of a nanometer-sized device developed by Carnegie Mellon scientists that demonstrates a new form of the Hall effect. For more than a century, the Hall effect has been taught with a simple picture that electricity flows through a material, a magnetic field pushes the moving charges sideways, and a voltage…
