The purpose of this article is to investigate the effect of hydriding of metallic glasses Fe{sub 78}Si{sub 9}B{sub 13} and Co{sub 78}Si{sub 9}B{sub 13} on their electron structure. The samples of alloys used for investigation contained the same percentages of boron and silicon, whereas the main components of the alloys were interchangeably two metals of the 3-d transition metals triad. Because of the amorphous character of the samples and the characteristic occurrence of unsaturated covalent bonds in amorphous materials, the process of hydriding the metallic glasses was expected to have an effect on electron phenomena. In the structure of unsaturated covalent bonds, the introduced hydrogen may lead to the occurrence of an additional electron energy band or to increased concentration of electrons in the already existing energy bands. Therefore, it was decided that the effect of hydriding on the spectrum of characteristic electron energy losses (EELS), Hall effect, transverse magnetoresistance, and electric resistance should be investigated.
