      abstract     = {Many fascinating magnetic effects emerge at interfaces
                      between layers with different magnetic orders. Interface
                      confinement is intimately related to the magnetic proximity
                      effect, which typically has a spatial extent of only a few
                      atomic layers. This short extent is due to the underlying
                      physical coupling mechanisms, such as the exchange
                      interaction, the Dzyaloshinsky-Moriya interaction, interface
                      states, rehybridization, and reconstruction, all of which
                      are highly localized. We use off-axis electron holography to
                      reveal an exceptionally long-range magnetic proximity effect
                      reaching ∼40 nm at a ferromagnetic (FM)/ paramagnetic (PM)
                      interface in La0.7Sr0.3MnO3 (LSMO). This wide extent arises
                      from carrier diffusion and drift across the interface, which
                      changes the Mn3+/Mn4+ ratio and thereby the density of
                      magnetic moments and local Curie temperature. We determine
                      the carrier concentration dependence of the Curie
                      temperature and unravel the physical mechanism of the
                      electrostatic extension of magnetic proximity effects,
                      fundamentally reshaping our understanding of micromagnetism
