      abstract     = {Magneto-ionic control of magnetism is a promising route
                      toward the realization of non-volatile memory and memristive
                      devices. Magneto-ionic oxides are particularly interesting
                      for this purpose, exhibiting magnetic switching coupled to
                      resistive switching, with the latter emerging as a
                      perturbation of the oxygen vacancy concentration. Here, we
                      report on electric-field-induced magnetic switching in a
                      La0.7Sr0.3MnO3 (LSMO) thin film. Correlating magnetic and
                      chemical information via photoemission electron microscopy,
                      we show that applying a positive voltage perpendicular to
                      the film surface of LSMO results in the change in the
                      valence of the Mn ions accompanied by a metal-to-insulator
                      transition and a loss of magnetic ordering. Importantly, we
                      demonstrate that the voltage amplitude provides granular
                      control of the phenomena, enabling fine-tuning of the
                      surface electronic structure. Our study provides valuable
                      insight into the switching capabilities of LSMO that can be
                      utilized in magneto-ionic devices.},
