Abstracts

EN

Nanocrystalline alloy of FINEMET and NANOPERM-type were studied by the Mössbauer spectroscopy after atmospheric corrosion up to 10 months. Corrosion process has an influence on the magnetic microstructure, which reflects at the Mössbauer parameters as a change in direction of net magnetic moment, intensity, and distribution of internal magnetic field. During corrosion process the most occurring tendency was the rotation of net magnetic moment out of the ribbon plane. This behaviour might result from the internal stress produced during corrosion treatment. The observed changes in the average hyperfine field and shape of its distribution indicated the changes of the microscopic magnetic properties induced by corrosion damage. These results are compared with radiation corrosion.
