New perovskite CeBaMn2O6: A potential target system to achieve magnetoelectric coupling

We have synthesised the new perovskite CeBaMn2O6, which based in our enumeration of possible magnetoelectric coupling in perovskites is a potential target system to exhibit multiferroic properties. The data from WISH will allow us to refine the magnetic structure and assign a magnetic space group. This will reveal if there is any induced polarisation by the magnetic ordering (through considering the magnetic symmetry). Additionally, patterns collected above the magnetic ordering temperature will allow us to precisely refine the atomic displacement associated with Ce/Ba cation ordering, any octahedral rotations and orbital ordering that is expected to couple to the magnetic structure. The results will lead a broader understanding of the interplay between chemical and magnetic and orbital ordering degrees of freedom and how they may be coupled to produce novel magnetoelectric couplings.
