## Description

- description: A new A-site columnar-ordered quadruple perovskite, Gd2CuZnMn4O12,
    was synthesized by a high-pressure, high-temperature method at 6 GPa and 1500
    K. Its structural properties between 100 K and 800 K were investigated by synchrotron
    powder X-ray diffraction. It has space group Pmmn (No. 59) between 100 K and about
    450 K with a layered charge order (CO) of Mn3+ and Mn4+ cations at the perovskite
    B sites and space group P42/nmc (No. 137) above 475 K with one perovskite B site
    (having an average manganese oxidation state of +3.5). Anisotropic thermal expansion
    was observed as the c lattice parameter decreases with increasing temperature
    above 325 K. Temperature dependence of the unit-cell volume and the lattice parameters
    and differential scanning calorimetry measurements gave evidence that the CO transition
    (with TCO = 475 K) is of the second order. Gd2CuZnMn4O12 shows a ferrimagnetic
    transition below TC = 105 K with an additional decrease of magnetic susceptibilities
    below about 45 K, probably caused by a gradual increase of the ordered moments
    on the Gd sublattices coupled antiferromagnetically with the existent ferrimagnetic
    structure.
