TI - Pressure-mediated structural transitions in bulk EuTiO 3 JO - Physical review / B VL - 98 IS - 5 SN - 2469-9950 CY - Woodbury, NY PB - Inst. M1 - FZJ-2020-02927 SP - 054105 PY - 2018 AB - The high pressure structural phase diagram of EuTiO3 is revisited by means of single crystal x-ray diffraction at pressures below 30GPa. We report a transition at about 3GPa with a surprisingly small lattice distortion. At 23GPa we have detected a yet unknown transition into a new orthorhombic phase (space group Ibam). Combining our observations on structures obtained on single crystals and polycrystalline samples with complementary methods, such as electrical resistivity and nuclear forward scattering of synchrotron radiation measured on polycrystalline samples, we address issues relevant to chemistry and disorder.
