摘要

Two magnetic ordering transitions are found in InMnO_3, the paramagnetic to antiferromagnetic transition at ~118 K and a lower possible spin rotation transition near 42 K. Multiple length scale structural measurements reveal enhanced local distortion found to be connected with tilting of the MnO_5 polyhedra as temperature is reduced. Coupling is observed between the lattice and the spin manifested as changes in the structure near both of the magnetic ordering temperatures (at ~42 and ~118 K). External parameters, such as pressure, are expected to modify the coupling.
