Purpose: In the work, influence of chemical composition, as well as magnetic and electric properties on ability of metallic glass screens for shielding of not ionizing electromagnetic fields were analyzed. Design/methodology/approach: The groups of amorphous metallic alloys with iron, iron and nickel and cobalt matrix were selected for research. Samples of afore-mentioned metallic glasses were examined from the point of view of structure, magnetic, electric and mechanical properties. Findings: There is possibility of utilization of metallic amorphous materials for screens of not ionizing, electromagnetic fields especially in range of broad-band multi-layers screens with high efficiency of shielding in wide range of frequencies.

Research limitations/implications: Very good magnetic properties and parallel low electric conductivity of metallic glasses are not enough for construction of multi-layer broadband screen. Therefore for constructing broadband screen, which would attenuate much better in wider range of frequencies, we should seek solutions in multi-layers systems consisting of metallic glass fabrics, layers of large conductivity materials and nonmagnetic isolating layers. Problems of determining the number of layers, individual thickness of layer, materials in relation to optimum costs of the multi-layers screen metallic glasses are unsolved. Practical implications: Attenuation of metallic glass screens show very high possibilities of metallic glasses in solution of problem of shielding electromagnetic fields. Originality/value: There are two general direction of improvement of suppression efficiency of electromagnetic fields screens: research of new constructions of elastic screens, and investigation of new materials for screens join higher magnetic properties at high conductivity. In this second area, any possibilities exist in metallic nanomaterials in form of tapes and nanocomposites consisting magnetic powders with amorphous and nanocrystalline structure.
