## Description

- description: A-site-ordered quadruple perovskites, AA’3B4O12, can have 3d transition-metal
    at A’ and B sites and show complex magnetic interactions and behavior. Additional
    complexity appears when B-site-ordered arrangements are realized in AA’3B2B’2O12.
    In this work, A-site-ordered quadruple perovskites, RMn3Ni2Mn2O12 with R = Bi,
    Ce, and Ho, were prepared by a high-pressure, high-temperature method at about
    6 GPa and about 1500 K. The R = Bi and Ce samples were found to crystallize in
    space group Im-3 with a disordered distribution of Ni2+ and Mn4+ cations in one
    B site. On the other hand, the R = Ho sample crystallized in space group Pn-3
    and showed a partial ordering of Ni2+ and Mn4+ cations between two B sites. The
    structural data (and bond-valence sums) suggest that cerium has the oxidation
    state +3 that is unusual for such perovskites. Magnetic properties were investigated
    by magnetic susceptibility and specific heat measurements, which showed the presence
    of one magnetic transition near 36 K for R = Bi; there was evidence for the presence
    of two magnetic transitions near 27 K and 33 K for R = Ce and near 10 K and 36
    K for R = Ho. Curie-Weiss parameters were estimated for all samples from high-temperature
    magnetic measurements up to 750 K. The total effective magnetic moment for R =
    Ce also suggests the presence of Ce3+. Magnetic field of 90 kOe has the largest
    effect on specific heat of the R = Ho sample, and almost no effects on specific
    heat of the R = Bi sample.
