In physics, the classical "Hall effect," discovered in the late 19th century, describes how a transverse voltage is generated when an electric current is exposed to a perpendicular magnetic field.

An international research team has discovered the anomalous Hall effect in a collinear antiferromagnet. More strikingly, the anomalous Hall effect emerges from a non-Fermi liquid state, in which ...
