Paper: Preferential quenching of 5d antiferromagnetic order in Sr3(Ir1−xMnx)2O7
Our paper exploring the effect of transition metal ion substitution in the Jeff=1/2 Mott insulator Sr3Ir2O7 was published in J. Phys. Cond Matt. Here combined neutron and resonant x-ray scattering studies revealed an unusual suppression of the Ir order upon 3d Mn substitution, while Mn spin order persists across the entire phase diagram. This reveals an unusual percolation mechanism that differs between the 5d and 3d cations and likely arises due to extended exchange on the 3d Mn sublattice.
