Structure, Mössbauer spectroscopy and vibration phonon spectra in valence-bond force-field model approach for distorted perovskites AFeO3 (A = La, Y)

Two distorted perovskite orthoferrites, AFeO3 (A = La, Y), were synthesized by solid-state reaction method and investigated using the experimental techniques, e.g., X-ray diffraction, Mössbauer spectra, and infrared and Raman spectra at room temperature. The internal hyperfine magnetic field at La-s...
