Using small scattering of X-rays, ferromagnetic resonance and Mössbauer spectroscopy, the structure and magnetic properties of the amorphous ribbons Fe 80Si 6B 14 are studied. It is shown that the high temperature treatment of the melts before spinning results in short-range atomic ordering of the liquid solution inherited due to rapid quenching. Two kinds of non-equiaxial clusters having different magnetic properties are the reason for the magnetic anisotropy in the absence of the crystal structure. A phenomenological model of magnetic anisotropy is proposed. The increase in the temperature of the heat treatment affects the magnetization of the cluster systems, does not change the saturation magnetization and decreases magnetic anisotropy. ► High-temperature treatment over liquid FeSiB alloy enhancing short-range atomic order, which is inherited by the amorphous state. ► Two kinds of atomic clusters have different magnetic properties and are the reason of the remarkable magnetic anisotropy. ► A phenomenological model of magnetic anisotropy of the amorphous ribbon is proposed.
