Ca$_2$MnO$_4$ structural path: Following the negative thermal expansion at the local scale
The oxygen octahedral rotations in Ca$_2$MnO$_4$, the first member of the $\textrm{Ca O ( CaMnO}_3)_n$ Ruddlesden-Popper family, is probed through a set of complementary techniques, including temperature-dependent neutron and x-ray diffraction, combined with local probe studies and ab initio calcula...
