▎ 摘　　要

NOVELTY - The method comprises disposing a single-layer graphene nano-powder on the front side of the two-dimensional ferromagnetic/anti-ferromagnetic heterojunction sample, focusing the laser light emitted by the laser on the plane, where the single-layer graphene nano-powder is located to control the movement of the sample, and adjusting the laser exerts out-of-plane pressure on the sample, and the interlayer spacing of the heterojunction by changing the laser power in the process of moving to achieve the regulation of exchange bias effect, where the lower layer of the heterojunction is a two-dimensional ferromagnetic material, and the upper layer is a two-dimensional anti-ferromagnetic material. USE - Method for regulating and controlling two-dimensional ferromagnetic/anti-ferromagnetic heterojunction exchange bias, which is used in spinning electronics. Can also be used in giant magneto-resistive device, magnetic sensor, hard disk drive and magnetic device. ADVANTAGE - The method: solves the problem that the blocking temperature is low and exchange bias field is small, and it cannot be effectively optimized; continuously adjusts the exchange bias effect in the Van der Dehua magnetic heterojunction, and improves the controllability of the effect. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a device for regulating and controlling two-dimensional ferromagnetic/anti-ferromagnetic heterojunction exchange bias. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic diagram of a device for implementing a laser shock reinforcement process on the prepared heterojunction.
