## Description

- description: The appearance of spin-induced ferroelectric polarization in the so-called
    type-II multiferroic materials has received a lot of attention. The nature and
    mechanisms of such polarization were intensively studied using perovskite rare-earth
    manganites, RMnO3, as model systems. Later, multiferroic properties were discovered
    in some RFeO3 perovskites and possibly in some RCrO3 perovskites. However, R2NiMnO6
    double perovskites have ferromagnetic structures that do not break the inversion
    symmetry. It was found recently that more complex magnetic structures are realized
    in A-site-ordered quadruple perovskites, RMn3Ni2Mn2O12. Therefore, they have potential
    to be multiferroics. In this work, dielectric properties in magnetic fields up
    to 9 T were investigated for such perovskites RMn3Ni2Mn2O12 with R = Ce to Ho
    and for BiMn3Ni2Mn2O12. The samples with R = Bi, Ce, and Nd showed no dielectric
    anomalies at all magnetic fields, and dielectric constant decreases with decreasing
    temperature. The samples with R = Sm to Ho showed qualitatively different behavior,
    when dielectric constant started increasing with decreasing temperature below
    certain temperatures close to the magnetic ordering temperatures, TN. This difference
    could suggest different magnetic ground states. The samples with R = Eu, Dy, and
    Ho still showed no anomalies on dielectric constant. On the other hand, peaks
    emerged at TN on dielectric constant in the R = Sm sample from about 2 T up to
    the maximum available field of 9 T. The Gd sample showed peaks on dielectric constant
    at TN between about 1 T and 7 T. Transition temperatures increase with increasing
    magnetic fields for R = Sm, and decrease for R = Gd. These findings suggest the
    presence of magnetic-field-induced multiferroic states in the R = Sm and Gd samples
    with intermediate ionic radii. Dielectric properties at different magnetic fields
    are also reported for Lu2NiMnO6 for comparison.
