Electric ?eld gradient in FeTiO3 by nuclear magnetic resonance and ab initio calculations
Original language description
Temperature dependence of nuclear magnetic resonance (NMR) spectra of 47Ti and 49Ti in polycrystalline ilmenite FeTiO3 was measured in the range from 5 to 300 K under an external magnetic ?eld of 9.401 T. NMR spectra collected between 300 and 77 K exhibit a resolved quadrupole splitting. The electric ?eld gradient (EFG) tensor was evaluated for Ti nuclei and the ratio of 47Ti and 49Ti nuclear quadrupole moments was re?ned during the ?tting procedure. Below 77 K, the fine structure of quadrupole splitting disappears due to the enormous increase of anisotropy. As a counterpart, ab initio calculations were performed using full potential augmented plane waves + local orbitals. The calculated EFG tensors for Ti and Fe were compared to the experimental onesevaluated from NMR and the Mossbauer spectroscopy experiments.
