                      of mass action is proposed to clarify the details of the
                      chemistry of point defects for donor-doped YbxCa1-xMnO3.
                      DC-conductivity measurements were carried out in a wide
                      range of partial pressure of oxygen p(O2) ≈ 10−1 down to
                      10-19 MPa at 750⁰C for the first time without
                      disintegrating the ceramic sample through reduction. A
                      comparison of the experimental observations and the
                      theoretical defect chemical models clearly shows the
                      possibilities for controlling charge carriers in dependence
                      of partial pressure of oxygen p(O2) and dopant
                      concentration. The origin of a plateau state, of a drastic
                      decrease in conductivity in the intermediate and reduction
                      p(O2) regimes are figured out, respectively. In addition,
                      the kind and concentration of the electronic and ionic
                      majority charge carriers are determined and formulated
                      according to the proposed defect chemical model.
                      Furthermore, phase transitions were studied in a wide range
                      of p(O2) at elevated temperatures},
