Synthesis of Magnetic Thin Films on Glass Substrates Using NH₃ Vapors

Abstract:

Magnetic thin films in nanometer range have been synthesized on the glass substrates. The synthesis has been carried out using Fe²⁺ and Fe³⁺ ions in a PVA solution in H₂O. A different approach has been used for the synthesis of the magnetic thin films by using NH₃vapors. Obtained films have been characterized by scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray diffraction (XRD) and magnetic property measurement system (MPMS). The size and distribution of the magnetite nanoparticles inside the films depends upon the supply of the NH₃ vapor. For large exposure time of NH₃ vapors, film contains magnetite nanoparticles of size up to 80 nm. While for low exposure time of NH₃ vapors_, small magnetite nanoparticles of size nearly 20 nm have been obtained. The particles are independent to each other with no aggregation and are uniformly distributed inside the film.
