The temperature dependence of Mössbauer quadrupole splitting of 57 Fe 2+ in GeFe 2 O 4 is theoretically analysed by taking into account the effect of orbit—lattice interactions from 77 to 1000 K. It shows a good agreement between theoretical and experimental results, brings consistency between Mössbauer and magnetic susceptibility measurements, and emphasizes the importance of the dynamic crystal field approach over a wide range of temperatures.
