Method for strengthening abnormal hall effect

The invention provides a method for strengthening an abnormal hall effect. The strength of a normal hall effect and an abnormal hall effect can be controlled by regulating and controlling a voltage. The method is carried out by the following steps: (1) preparing an electrode on a substrate by a pulsed laser deposition method; (2) preparing a ferroelectric film on an electrode layer; (3) plating the ferroelectric film with two cross-shaped Pt films; (4) welding Ag at six endpoints of Pt or welding silver paste points at the endpoints of the Pt; and (5) measuring the hall effect. The Pt is deposited on an insulated magnetic material, so that the conductivity and the magnetism can be measured and represented; and the strength of the normal hall effect and the abnormal hall effect can be directly regulated and controlled through an external electric field.
