Structure, conductive and reflective properties of amorphous nanogranular composites (CoFeB)$_x$+(SiO$_2$)$_{1-x}$

The results of experimental studies of the structure, conductive and microwave reflective properties in the frequency ranges of 8–12 GHz and 25–36 GHz of amorphous nanogranular composites (CoFeB)$_x$+(SiO$_2$)$_{1-x}$, 32.79 $<x<$ 52.00 at.%, with a thickness of 1.11–2.54 $\mu$m, deposited on a lavsan substrate with a thickness of about 20 $\mu$m, are presented. The influence of the content of the CoFeB ferromagnetic alloy on the conductive and reflective properties of the films is estimated. The results of experimental effects of magnetic fields with induction up to 0.3 T on the reflection coefficient of microwave waves of composite films are presented.
