Preparation and Physical Properties of Flexible Magnetoelectric Functional Materials

Flexible electronic devices have the advantages of flexibility, easy portability, and potential low-cost manufacturing. They have important application prospects in medical, information, and energy fields, and have attracted widespread attention. The most ideal flexible electronic devices, such as flexible wearable devices, require all components to be flexible, including flexible power sources, flexible circuits, flexible displays, flexible sensing, and flexible storage. It can be seen that how to realize the flexibility of traditional functional materials, understand the evolution law of material functional properties under stress/strain environment, and master the methods to control the functions of materials and devices under multiple physical fields have become very important issues. On the other hand, magnetic materials are an important part of electronic devices. The preparation of magnetic thin films on flexible substrates and the study of their magnetoelectric properties are an important basis for the development of flexible magnetoelectronic/spintronic devices.

Preparation and Physical Properties of Flexible Magnetoelectric Functional Materials

This direction mainly focuses on the research work of flexible magnetoelectric functional materials and devices, including:

(1) Develop high-quality flexible magnetoelectric functional materials preparation technology;

(2) To study the evolution and regulation of physical properties of magnetoelectric functional materials and devices under the action of multiple physical fields (force, magnetism, electricity, heat, etc.). The research goal is to master the preparation process of flexible magnetoelectric thin films with controllable electromagnetic properties (stress-sensitive thin films and strain-insensitive thin films), and obtain multi-physics field effects on the electromagnetic properties of flexible magnetoelectric thin films (magnetic anisotropy, coercivity, Regulation of high-frequency permeability and giant magnetoresistance effect).

The Flexible Magnetoelectric Functional Materials and Devices Team is an innovative research platform affiliated to the Key Laboratory of Magnetic Materials and Devices of the Chinese Academy of Sciences and the Key Laboratory of Magnetic Materials and Its Application Technology of Zhejiang Province.
