Probing magnetic correlations in Mn2Mo3O8 under applied pressure

Layered A2Mo3O8 materials (where A = Mn, Fe, Co or Ni) exhibit alternating layers of MoO6 Kagome and AO4 tetrahedral/AO6 octahedral honeycomb layers. The MoO6 layer exhibits a orbital driven Peierls trimerization of the molybdenum cations and as such magnetic character arises solely from the transition metal honeycomb layer. As a result, a vast range of magnetic order and magnetoelectric behaviour depending on the identity of the A cation have been reported. The cobalt and iron analogues have also been shown to be extremely sensitive to external stimuli such as applied magnetic fields or chemical doping. Applied pressure can therefore, also be expected to enable the tuning of magnetic behaviour but to date limited work has been performed in this area. Recently we reported (J. Mater. Chem. C, 2025) a comprehensive study of the magnetic behaviour in Mn2Mo3O8. We now seek to understand the effects of applied pressure on the structural and magnetic properties of this material.
