      abstract     = {Samples with the composition Ce0.9Gd0.1MnxO2−δ with x =
                      0.01, 0.02, and 0.05 Mn-addition were prepared by mixed
                      oxide route from Ce0.9Gd0.1O2−δ and MnO2 and sintered at
                      1300 °C. The electronic conductivity was measured using a
                      modified Hebb-Wagner technique, the electrical conductivity
                      was investigated by impedance spectroscopy, and oxygen
                      permeation was measured for the sample with x = 0.05. An
                      increase of the electronic partial conductivity with
                      increasing Mn addition was observed, which can be attributed
                      to an additional Mn 3d-related state between the top of the
                      valence band and the bottom of the Ce 4f band. The grain
                      boundary conductivity was found to be suppressed for low Mn
                      contents, but enhanced for the sample with x = 0.05.},
