Magnetic heterogeneous metal nanomaterials have many excellent properties on magnetics and electromagnetism. Thus the research of the controllable synthesis, magnetics, electricity and magnetoelectric coupling properties is of great scientific importance and application values. This project will synthesize different shapes and structure-controlled magnetic heterogeneous metal nanomaterials by physical and chemical preparing methods. Then we study the relationship between the synthesis method, reaction condition and morphology, size, structure, composition to develop the controllable synthesis method for special structure magnetic heterogeneous metal nanomaterials; We character grain composition, atomic matching, interface defect and electronic structure of the nanomaterials by different advanced transmission electron microscopy (TEM); We explore the differences of magnetics and electricity properties, etc, between the special structure magnetic heterogeneous metal nanomaterials and single component structure nanomaterials by measuring magnetics, electricity and magnetoelectric coupling properties, etc. Finally, we explore the interface control of magnetic heterogeneous metal nanomaterials and magnetoelectric coupling properties research integration with computing simulation to develop the latest magnetoelectric coupling system and mechanisms between the magnetic and electrical coupling properties, which will propel the application of sensing and information areas.
