Structural and magnetic properties of Fe doped CeO₂ thin films Available to Purchase

Pure and Ce_0.95Fe_0.05O₂ thin films have been fabricated on LaAlO₃ (100) substrate using pulsed laser deposition techniques at 200mTorr oxygen partial pressure and then characterized by various techniques viz. X-ray diffraction, atomic force microscopy, NEXAFS, and dc- magnetization measurements to explore the structural and magnetic properties of pure and Fe doped CeO₂ thin films. The XRD patterns indicate that pure and Ce_0.95Fe_0.05O₂ films have single phase polycrystalline behavior. The surface roughness measured using AFM microscopy found to decrease with Fe doping and revealed that both the films are nanocrystalline. The electronic structure measured at Fe L_3,2 edge infer that Fe-ions in mixed valence states (Fe³⁺ and Fe²⁺) in Fe doped CeO₂film. DC-magnetization measurements showed that pure and Fe doped CeO₂ films have ferromagnetic ordering at room temperature.
