    The paper presents studies of annealing effect on the magnetic properties of the bulk Fe62Co10Y8B20alloy in the form of rods. The thermal treatment was performed at the temperature well below the crystallization temperature. Structure, revealed by X-ray diffraction and Mössbauer spectroscopy and magnetic properties in high magnetic fields in the Fe62Co10Y8B20alloy after fabricated and after the annealing were studied. We have stated that the investigated alloy was fully amorphous. It is due to the stress relieving of the sample. Using a vibrating sample magnetometer the magnetization in high magnetic fields was studied. For both the sample after solidification and after heat treatment, the magnetization process in the area called "the approach to ferromagnetic saturation" is affected by free volumes. In addition, the heat treatment improved the magnetic properties and increased the packing density of atoms.
