      Masó, Nahum; Beltrán Mir, Héctor; Prades Tena, Marta; Cordoncillo, Eloisa; West, Anthony R. Royal Society of Chemistry (2014)
      The bulk conductivity at room temperature of Ca-doped BiFeO3 ceramics is p-type and increases reversibly by up to 3 orders of magnitude under the influence of a small dc bias voltage in the range B3 to 20 V mm1 . The ...
