A fundamental study on Co‐based metallic glasses has been conducted. The study focused on understanding the changes of the properties and structures of an Fe‐B‐Si glass as a function of Co, Co‐Ni, Co‐Mn, and Co‐Ni‐Mo additions. The separate addition of Co, Co‐Ni, Co‐Mn, and Co‐Ni‐Mo elements was successful in such a way that four new metallic glasses were produced. The compositions of the new glasses are Fe 66 Co 18 B 15 Si 1 , Co 66 Fe 4 B 14 Si 15 , Co 76 Fe 2 Mn 4 B 12 Si 6 , and Co 69 Fe 4 Mo 2 B 12 Si 12 . Consequently, an evaluation of the physical and magnetic properties was determined. Furthermore, the internal and surface structures of the glasses have been characterized by a transmission electron microscope (TEM), and a scanning tunneling microscope (STM), 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 structures of the glasses is established.
