    • Structure and Magnetism in Sr1-xAxTcO3 Perovskites. The importance of the A-site cation. 

      Reynolds, Emily; Avdeev, Maxim; Thorogood, Gordon J; Poineau, Frederic; Czerwinski, Kenneth R; Kimpton, Justin A; Yu, Michelle; Kayser, Paula; Kennedy, Brendan J (Amercian Physical Society, 2017)
      The Sr1-xBaxTcO3 (x = 0, 0.1, 0.2) oxides were prepared and their solid-state and magnetic structure studied as a function of the temperature by x-ray and neutron powder diffraction. The refined Tc moments at room temperature ...
    • Thermal Expansion Behavior in TcO2. Towards breaking the Tc-Tc bond. 

      Reynolds, Emily; Zhang, Zhaoming; Avdeev, Maxim; Thorogod, Gordon J; Poineau, Frederic; Czerwinski, Kenneth R; Kimpton, Justin A; Kennedy, Brendan J (ACS, 2017)
      The structure of TcO2 between 25 and 1000 °C has been determined in-situ using powder diffraction methods and is found to remain monoclinic in space group P21/c. The thermal expansion in TcO2 is highly anisotropic with ...
