Strategic Insights

— 1 min read

Research published in the Studia Universitatis Babes-Bolyai Chemia journal by the Romanian Academy has detailed significant advancements in nanotechnology, specifically in the field of Nd-Fe-B thin films. The research, led by Ana-Maria POPESCU and co-authored by Mihai ANASTASESCU, Jose CALDERON MORENO, Elena Ionela NEACSU, Olga DEMIDENKO MINCHUKOVA, Kazimir YANUSHKEVICH, and Virgil CONSTANTIN, has successfully grown nanostructured thin layers on glass substrates using the "flash" evaporation (FE) method.

Key Takeaways:

  • The research demonstrated the feasibility of growing nanostructured thin layers of Nd-Fe-B on glass substrates using the FE method.
  • X-ray diffraction (XRD), scanning electron microscopy (SEM), atomic force microscopy (AFM), and X-ray photoelectron spectroscopy (XPS) were used to analyze the microscopic and surface structure of the thin films, confirming their nanostructured nature.
  • The specific magnetization of the films was measured to be in the range of 85-140 A x m2 x kg-1 at 77 K.
  • Corrosive action on the thin films resulted in the formation of Fe3O4 and free iron ions on the surface, increasing the specific magnetization value.
  • The research also confirmed the presence of Fe3O4, FeOOH, and Nd(OH)3 on the surface of the nanometric Nd-Fe-B layer.

Statistics:

  • The specific magnetization of the films before corrosion did not exceed 85 A x m2 x kg-1 at 77 K.
  • After corrosive action, the specific magnetization value increased to 140-155 A x m2 x kg-1.
  • The XPS measurements confirmed the presence of Fe3O4, FeOOH, and Nd(OH)3 on the surface of the nanometric Nd-Fe-B layer.
