A method for regulating the interaction of ferromagnetic multilayer films belongs to the technical field of high-density information storage and sensing. Platinum Pt / cobalt Co / tantalum Ta multilayer film is deposited on Si substrate after surface acid treatment and ultrasonic cleaning. After the deposition is completed, arsenic and As ions are implanted into the film, and the electron orbital occupation at the interface is adjusted by As ions to affect the spin-orbit coupling strength of the multilayer film, thereby regulating the DM interaction of the ferromagnetic multilayer film. The present invention directly adjusts the orbital occupancy of the multilayer film interface through the method of As ion implantation, thereby changing the spin-orbit coupling effect, and finally regulating the DM interaction of the multilayer film interface. This method does not depend on a special material system and is universal Moreover, this method can achieve different degrees of regulation of DM interaction by changing parameters such as implantation ion source, implantation energy, and implantation density. The process is simple, the cost is low, and the controllability is strong. It can be applied to future spintronics technology .
