title = "Low temperature structural phase transition in the Ba2CaMoO6 perovskite",
abstract = "Ba2CaMoO6 was synthesized by a solid state method. The crystal structure adopts the cubic Fm-3m space group at room temperature with lattice parameters of 8.3775 (9) {\AA}. Upon cooling, Ba2CaMoO6 was determined to have a structural phase transition to tetragonal I4/m (a = 5.9051 (2) {\AA} and c = 8.3872 (4) {\AA}) near 200 K. The phase transition was probed structurally by synchrotron and neutron diffraction and thermodynamically by specific heat and differential scanning calorimetry measurements. This structural phase transition will deepen our understanding of the perovskite family, especially the formation of perovskites that break corner sharing networks.",
