Abstract
A charge-carrier Hall-effect sensor comprising: a semiconductor or a semimetal layer; a pair of electric current contacts in electrical contact with the semiconductor or semimetal layer and separated in a first longitudinal direction along a first electric current channel; a pair of voltage contacts in electrical contact with the semiconductor or semimetal layer and separated in a second transverse direction, orthogonal to the first direction, and positioned on either side of the electric current channel; an electrically insulating layer underlying the semiconductor or the semimetal layer; and a ferromagnetic layer underlying the electrically insulating layer comprising at least one region having a magnetic moment with a component perpendicular to a plane comprising the pair of electric current contacts and the pair of voltage contacts.
