The effect of ferromagnetic impurities in electromagnetic absorbers is studied. It has established that a small amount of magnetic powder in composite structure influence on attenuation and reflection characteristics of shielding material. These magnetic inclusions can increase the attenuation at 15 dB and reflection coefficient at 2,5 dB in comparison with dielectric samples. The compound with powders of silica and nickel-zinc ferrite as a base of shielding composite has investigated. The
