Abstract
X-ray measurements of the mean square amplitude of lattice vibrations previously made on polycrystalline samples were now repeated on single crystals of composition Mn1·66Fe1·33O4 and NiFe2O4. The greater value of the mean square amplitude for the Mn-ferrite is consistent with results on polycrystalline samples and is a further confirmation of the existence of local Jahn-Teller distortion in manganese ferrite.
