      abstract     = {Measurements of both the inclusive and differential
                      production cross sections of a top-quark-antiquark pair in
                      association with a $Z$ boson ($t\bar{t}Z$) are presented.
                      Final states with two, three and four isolated leptons
                      (electrons or muons) are targeted. The measurements use the
                      data recorded by the ATLAS detector in $pp$ collisions at
                      $\sqrt{s}=13$~TeV at the Large Hadron Collider during the
                      years 2015-2018, corresponding to an integrated luminosity
                      of $140$ fb$^{-1}$. The inclusive cross section is measured
                      to be $\sigma_{t\bar{t}Z}= 0.86 \pm 0.04~\mathrm{(stat.)}
                      \pm 0.04~\mathrm{(syst.)}~$pb and found to be in agreement
                      with the most advanced Standard Model predictions. The
                      differential measurements are presented as a function of a
                      number of observables that probe the kinematics of the
                      $t\bar{t}Z$ system. Both absolute and normalised
                      differential cross section measurements are performed at
                      particle- and parton-level for specific fiducial volumes,
                      and are compared with theoretical predictions at NLO+NNLL.
                      The results are interpreted in the framework of the Standard
                      Model Effective Field Theory and used to set limits on a
                      large number of dimension-6 operators involving the top
                      quark. The first measurement of spin correlations in
                      $t\bar{t}Z$ is presented: the results are in agreement with
                      the Standard Model expectations, and the null hypothesis of
                      no spin correlations is disfavoured with a significance of
                      $1.8$ standard deviations.},
