A fundamental study has been conducted on Fe{sub 78}B{sub 13}Si{sub 9} metallic thin ribbon in order to understand the changes in the properties and structures of the glass as a function of Cr and Ni-Mo additions. The separate additions of Cr and Ni-Mo were successful in producing two new metallic thin glasses with the compositions Fe{sub 77}Cr{sub 2}B{sub 16}Si{sub 5} and Fe{sub 74}Ni{sub 4}Mo{sub 3}B{sub 17}Si{sub 2}. The study was focused on evaluating the physical and magnetic properties of these glasses with respect to the Cr and Ni-Mo additions. In addition, characterization of the internal and the surface structures of the glasses was conducted using transmission electron microscopy and scanning tunneling microscopy, respectively. A comparison between the internal and surface structures of the glasses was carried out on both amorphous and crystalline forms. As a result, a correlation between the properties and the structures of the glasses was established.
