Abstract

We report the NMR spectra of gallium substituted magnetite measured at temps. 4.2, 77 and 273 K. A single crystal of Fe3-xGaxO4, x = 0.05 has been prepd. by a floating zone technique. The Ga-lines found in the NMR spectrum above Verwey temp. Tv .apprx. 117 K indicate a preference of Ga substitution into the tetrahedral A-sites. The well-resolved structure of Ga-lines has been identified and assigned to both Ga isotopes below TV. A weak quadrupolar interaction contributes only to the line broadening. [on SciFinder (R)]
