Purpose: The investigation results of crystallization of amorphous Co77Si11.5B11.5 alloy in tape form, obtained by melt spinning method during annealing in temperature range 373-873 K with step of 50 K in time 1 h, have been presented in the paper. Design/methodology/approach: The following experimental techniques were used: X-ray diffraction (XRD), electrical resistivity in situ measurements (four-point probe) static and dynamic measurements of magnetic properties (magnetic balance, fluxmeter, Maxwell-Wien bridge). Findings: The changes of magnetic properties connected with the structure changes involved by crystallization process have been investigated of amorphous Co77Si11.5B11.5 alloy. Practical implications: Amorphous magnetic materials have been around for some time and their applications can be found in many types of industrial products. They include transformers, motors, and a wide variety of magnetic components in sensors, power electronics, electrical energy control/management systems, telecommunication equipment and pulse power devices. Originality/value: It has been stated that heat treatment leads to crystallization leads to a significant increase of the initial magnetic permeability.
