Mössbauer evidence for Fe2+−Fe3+ ordering in magnesioferrochromite
- 24 Downloads
Mössbauer absorption spectra of a natural chromite from Shanxi province of China were measured in a temperature range from 12K to 800K. Each spectrum at low temperature can be fitted to three doublets; the first two are attributed to tetrahedral (T) site Fe ions and the third one to octahedral (M) site Fe ions. As a main result. our data strongly supported an ordered distribution with Fe2+ in T-site and Fe3+ in M-site for chromite studied.
