According to the magneto-electric coupling device, the device cost can be greatly reduced, the integration level can be improved, and the magneto-electric coupling device capable of promoting the ion regulation can be advanced into the application field.

Description

technical field [0001] The invention relates to the field of materials, in particular to a magnetoelectric coupling device. Background technique [0002] Magnetism and electricity are two fundamental properties of matter. In the past ten years, researchers have been working hard to explore material systems with coexistence and coupling of magnetism and electricity, that is, to realize magnetoelectricity and electromagnetism in materials. Materials with magnetic and electrical coupling can effectively control their own two degrees of freedom of charge and spin. Therefore, materials with magnetoelectric coupling play an important role in the fields of semiconductors, storage, sensors, etc., and will greatly promote the development of modern electronics. The development of the information industry. [0003] Single-phase multiferroic materials are typical materials with magnetoelectric coupling properties. However, the magnetoelectric coupling strength of single-phase multifer...
