Abstract

A current of electrons traversing a landscape of localized spins possessing non-coplanar magnetic order gains a geometrical (Berry) phase, which can lead to a Hall voltage independent of the spin–orbit coupling within the material—a geometrical Hall effect. Here we show that the highly correlated metal UCu5 possesses an unusually large controllable geometrical Hall effect at T
