      abstract     = {As one of the alternative to conventional sintering, the
                      application of electrical fields during sintering has
                      aroused interest since decades, aiming at reducing the
                      sintering time as well as improving the targeted material
                      properties. Field assisted sintering (FAST) has undergone
                      rapid development in the last years, as it provides a
                      platform for manufacturing materials which are difficult or
                      even impossible to be produced by conventional sintering
                      [1]. More recently, strong focus is put on ‘flash
                      sintering’ in the academia, where the densification
                      completes within seconds [2]. However, the governing
                      principles behind the field assisted sintering are still
                      unveiled. In this work, the sintering of yttria-doped ceria
                      samples (10 mol $\%$ yttrium doped ceria, 10YDC,and 0.1 mol
                      $\%$ yttrium doped ceria, 01YDC) was studied under
                      alternating electrical fields with a frequency of 50 Hz and
                      field strengths significantly weaker than those required for
                      the ‘flash regime’. For the first time, the dependence
                      of sintering parameters on the applied electrical fields was
                      investigatedwith constant sample temperatures, which was
                      ensured by direct temperature measurement inside the sample
                      and by thermo-electric finite element simulations. This
                      excluded the macroscopic Joule heating and allowed to
                      investigate the occurring mechanisms. In addition, the
                      symmetric behavior under compressive and tensile loading
                      could be experimentally verified for the first time. This
                      part of study was done during a research stay in National
                      Institute for Materials Science (NIMS), Japan. [...]},
