•We study magnetic and transport properties of Co–Si–B based metallic glasses.•Intervals of thermal stability of the existing phases have been determined.•We calculated paramagnetic moments per transition metal atom μTM.•Possibility of the cluster structure of studied alloys is discussed.•Influence of heat treatment on μTM and the Curie temperature is defined.
The structure, magnetic and resistivity characteristics of Co–Si–B metallic glasses containing complex dopants have been investigated. The intervals of thermal stability of the phases existing in the alloys studied have been determined. The temperature dependences of the resistivity were shown to be essentially nonlinear up to a certain temperature, evidencing for the contribution of several scattering mechanisms. Magnetic and resistivity behavior of these alloys are substantially governed by the phase separation within the region of the amorphous state stability and magnetic clusters formation. In the as-cast alloys these clusters are estimated to contain 2–4 Co atoms. Heat treatment significantly affects the structure and magnetic properties. It leads to increase of the Curie temperature and localized magnetic moment, whereas the crystallization temperature remains almost invariable.
