## Description

- description: ABO3 perovskite materials with small cations at the A site, especially
    with ordered cation arrangements, have attracted a lot of interest because they
    show unusual physical properties and deviations from general perovskite tendencies.
    In this work, A-site-ordered quadruple perovskites, RMn3Ni2Mn2O12 with R = Nd,
    Sm, Gd, and Dy, were synthesized by a high-pressure, high-temperature method at
    about 6 GPa. Annealing at about 1500 K produced samples with additional (partial)
    B-site ordering of Ni2+ and Mn4+ cations, crystallizing in space group Pn-3. Annealing
    at about 1700 K produced samples with disordering of Ni2+ and Mn4+ cations, crystallizing
    in space group Im-3. However, magnetic properties were nearly identical for the
    Pn-3 and Im-3 modifications in comparison with ferromagnetic double perovskites
    R2NiMnO6, where the degree of Ni2+ and Mn4+ ordering has significant effects on
    magnetic properties. In RMn3Ni2Mn2O12, one magnetic transition was found at 26
    K (for R = Nd), 23 K (for R = Sm), and 22 K (for R = Gd), and two transitions
    were found at 10 K and 36 K for R = Dy. Curie-Weiss temperatures were close to
    zero in all compounds suggesting that antiferromagnetic and ferromagnetic interactions
    are of the same magnitude.
