anomalous Hall effect

anomalous Hall effect

[ə¦näm·ə·ləs ′hȯl i‚fekt] (electromagnetism) In a current-carrying conductor in a magnetic field, development of a transverse voltage resulting from the deflection of positive charge carriers (hole states) by the Lorentz force. The Hall effect in ferromagnetic metals, which arises from the unsymmetrical scattering of conduction electrons at magnetic moments.
