11B MAS NMR study of Ga1−xFexBO3 mixed crystals
Résumé
11 B MAS NMR Local structure Local disorder. a b s t r a c t : Mixed iron-gallium borate crystals Ga 1-x Fe x BO 3 have been studied by Magic Angle Spinning (MAS) NMR of 11 B isotope. Experimental MAS NMR spectra have been computer simulated using a laboratory-developed code. The quadrupole parameters and isotropic chemical shift for 11 B are consistent with threefold-coordination of boron atoms. A detailed fitting to the experimental NMR spectra reveals the existence of a certain local disorder in Ga 1-x Fe x BO 3 crystals.
