Purpose: This paper describes influence of heat treatment on changes on structure and magnetic properties of the amorphous Co77Si11.5B11.5 alloy. Design/methodology/approach: The following experimental techniques were used: X-ray diffraction (XRD), static and dynamic measurements of magnetic properties (magnetic balance, fluxmeter, Maxwell-Wien bridge). Findings: The crystallization process involved by heat treatment leads to significant changes of structure and magnetic properties of amorphous Co77Si11.5B11.5 alloy. Research limitations/implications: Practical implications: The attractive properties of Co-Si-B alloy are of special interest for basic research on the materials as well as for their potential applications, like magnetic sensors. According to the results presented in this paper the examined Co77Si11.5B11.5 alloy as a soft magnetic material may be used in noise filters, saturable reactors, miniature inductance elements for abating spike noise, zero-phase current transformers, and magnetic heads etc., i.e. devices which are expected to exhibit high levels of permeability at high frequencies. Originality/value: It has been shown that thermal annealing at temperature close to the crystallization temperature leads to a significant increase of the initial magnetic permeability.
