## Description

- description: Through a combination of magnetic susceptibility, specific heat, and
    neutron powder diffraction measurements we have revealed a sequence of four magnetic
    phase transitions in the columnar quadruple perovskite Er2CuMnMn4O12. A key feature
    of the quadruple perovskite structural framework is the complex interplay of multiple
    magnetic sublattices via frustrated exchange topologies and competing magnetic
    anisotropies. It is shown that in Er2CuMnMn4O12, this phenomenology gives rise
    to multiple spin-reorientation transitions driven by the competition of easy-axis
    single ion anisotropy and the Dzyaloshinskii–Moriya interaction; both within the
    manganese B-site sublattice. At low temperature, one Er sublattice orders due
    to a finite f-d exchange field aligned parallel to its Ising axis, while the other
    Er sublattice remains non-magnetic until a final, symmetry-breaking phase transition
    into the ground state. This nontrivial low-temperature interplay of transition
    metal and rare-earth sublattices, as well as an observed k = (0, 0, 1 2) periodicity
    in both manganese spin canting and Er ordering, raises future challenges to develop
    a complete understanding of the R2CuMnMn4O12 family.
