文摘
- •
Phase transformation has been confirmed from XRD analysis and Raman spectroscopy.
- •
XPS spectra showed that Fe3+ oxidation state dominates over Fe2+ state.
- •
Magnetic measurements showed ferromagnetic behaviour in these samples.
- •
Raman spectroscopy indicated spin-two phonon coupling in agreement with magnetic behaviour.
