Abstract:	The mean square amplitude of lattice vibrations $overline {u^2 }$ has been measured in the cubic part of the Mn_xFe_3-xO₄-system. The observed increase of the $overline {u^2 }$ -value with increasing content of Mn ions in the system is interpreted as that, with gradual occupation of more and more octahedral sites by Mn³⁺ ions towards higher values ofx, the number of locally distorted Mn³⁺O₆^2– octahedrons increases.
