(Finemet) were presented. Measurements were realized in the coaxial line in the frequency range 0, 2 - 10, 2 GHz. The new technique for measuring of permittivity and permeability of powdered materials was developed. The obtained data was compared with data of powder received from milling of well known ferrite - Yiitrium Garnet YIG class ferrite, named G-175.
