Microwave absorbing mechanism of soft magnetic alloy Fe85Si2Al6Cr7

The powders of amorphous nanocrystalline Fe85Si2Al6Cr7 were prepared by high energy ball milling for different times, and measured by XRD and network analyzer.

Summary:The powders of amorphous nanocrystalline Fe85Si2Al6Cr7 were prepared by high energy ball milling for different times, and measured by XRD and network analyzer. The results show that： 1） nanocrystalline microstructure remarkably improves the microwave permeability, and the permittivity is controlled effectively; 2） by adding proper dyeing auxiliary （such as copper phthalocyanine）, the magnetic properties of powders are improved when the particle sizes milled are excessively small.
