      abstract     = {Three-dimensional (3D) compensated MnBi2Te4 is
                      antiferromagnetic, but undergoes a spin-flop transition at
                      intermediate fields, resulting in a canted phase before
                      saturation. In this work, we experimentally show that the
                      anomalous Hall effect (AHE) in MnBi2Te4 originates from a
                      topological response that is sensitive to the perpendicular
                      magnetic moment and to its canting angle. Synthesis by
                      molecular beam epitaxy allows us to obtain a large-area
                      quasi-3D 24-layer MnBi2Te4 with near-perfect compensation
                      that hosts the phase diagram observed in bulk which we
                      utilize to probe the AHE. This AHE is seen to exhibit an
                      antiferromagnetic response at low magnetic fields, and a
                      clear evolution at intermediate fields through surface and
                      bulk spin-flop transitions into saturation. Throughout this
                      evolution, the AHE is super-linear versus magnetization
                      rather than the expected linear relationship. We reveal that
                      this discrepancy is related to the canting angle, consistent
                      with the symmetry of the crystal. Our findings bring to
                      light a topological anomalous Hall response that can be
                      found in non-collinear ferromagnetic, and antiferromagnetic
                      phases.},
