Abstract:
The results of studies of the experimental effect of magnetic fields with induction up to 0.3 T on the reflection coefficient of microwave waves of amorphous nanogranulated composites (CoFeB)$_x$+(SiO$_2$)$_{1-x}$, 27.38 $\le x\le$ 84.14 at.%, 493–862 nm thick, sprayed onto a lavsan substrate 0.02 mm thick, in the frequency range 26–37 GHz are presented. The frequency dependences of the reflection coefficient of microwave waves are given. The effect of the ferromagnetic alloy content on the microwave reflective properties of films under the influence of a magnetic field is estimated. The ratio of the maximum value of the reflection coefficient of microwave waves to the minimum in the first extremes is determined. It is shown that magnetic fields can change the values of the reflection coefficient of composites by a factor of 1.43–1.92.
