Structure and magnetic properties of the amorphous Co80Si9B11 alloy

Abstract

Purpose: The main aim of the paper was to study the influence of heat treatment on changes of structure and magnetic properties of the amorphous Co80Si9B11 alloy.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 crystallization process involved by heat treatment leads to significant changes of phase composition and magnetic properties of amorphous Co80Si9B11 alloy. The activation energy of this process was determined by Kissinger method, which yields Ec=3.0±0.2 eV.Practical implications: According to the results presented in the present paper the examined Co80Si9B11 alloy as a soft ferromagnetic material with high permeability may be utilized in construction of more inductive components and is of great technological interest.
