The channeling effect in electron‐induced X‐ray emission has proved useful as a method to get immediate information about the cation atom distribution between octahedral and tetrahedral positions in the recently synthesized spinels: ZnCr 0.4 Fe 1.6 O 4 , ZnCrFeO 4 and ZnCr 1.6 Fe 0.4 O 4 . It is concluded that the Zn atoms are in tetrahedral positions and the Cr atoms in octahedral positions. The Fe atoms also have a strong octahedral site preference, but the analysis indicates that ~5% of them are in tetrahedral positions.
