The microwave absorption properties of Y2Fe16Si@MOF and Y2Fe16Si@GO composites

The microwave absorption properties of Y2Fe16Si@MOF and Y2Fe16Si@GO composites

With the development in communication technology, severe electromagnetic wave radiation pollution has been created, resulting in electromagnetic interference and health hazards. Thus, materials with excellent microwave absorbing properties have become an urgent need. Magnetic particles with core-she...
