## Description

- description: Here, we report the results of a Mössbauer study on hyperfine electrical
    and magnetic interactions in quadruple perovskite BiMn7O12 doped with 57Fe probes.
    Measurements were performed in the temperature range of 10 K < T < 670 K, wherein
    BiMn6.9657Fe0.04O12 undergoes a cascade of structural (T1 = 590 K, T2 =442 K,
    and T3 = 240 K) and magnetic (TN1 = 57 K, TN2 = 50 K, and TN3 = 24 K) phase transitions.
    The analysis of the electric field gradient (EFG) parameters, including the dipole
    contribution from Bi3+ ions, confirmed the presence of the local dipole moments
    pBi, which are randomly oriented in the paraelectric cubic phase (T > T1). The
    unusual behavior of the parameters of hyperfine interactions between T1 and T2
    was attributed to the dynamic Jahn–Teller effect that leads to the softening of
    the orbital mode of Mn3+ ions. The parameters of the hyperfine interactions of
    57Fe in the phases with non-zero spontaneous electrical polarization (Ps), including
    the P1 to Im transition at T3, were analyzed. On the basis of the structural data
    and the quadrupole splitting Δ(T) derived from the 57Fe Mössbauer spectra, the
    algorithm, based on the Born effective charge model, is proposed to describe Ps(T)
    dependence. The Ps(T) dependence around the Im to I2/m phase transition at T2
    is analyzed using the effective field approach. Possible reasons for the complex
    relaxation behavior of the spectra in the magnetically ordered states (T < TN1)
    are also discussed.
