      abstract     = {The ability to create atomically perfect, epitaxial
                      heterostructures of correlated complex perovskite oxides
                      using state-of-art thin film deposition techniques has
                      generated new physical phenomena at engineered interfaces.
                      Here we report on the impact of growth kinetics on the
                      magnetic structure and exchange coupling at the interface in
                      heterostructures combining layers of antiferromagnetic
                      La1/3Sr2/3FeO3 (LSFO) and ferromagnetic La2/3Sr1/3MnO3
                      (LSMO) on (0 0 1)-oriented SrTiO3 (STO) substrates. Two
                      growth orders are investigated, (a) LSMO/LSFO/STO(0 0 1)
                      and (b) LSFO/LSMO/STO(0 0 1), where the LSFO layer is
                      grown by molecular beam epitaxy and the LSMO layer by high
                      oxygen pressure sputtering. The interface has been
                      investigated using electron microscopy and polarized neutron
                      reflectometry. Interdiffusion over seven monolayers is
                      observed in LSMO/LSFO (a) with an almost $50\%$ reduction in
                      magnetization at the interface and showing no exchange
                      coupling. However, the exchange bias effect ( mT at 10 K)
                      could be realized when the interface is atomically sharp, as
                      in LSFO/LSMO (b). Our study therefore reveals that, even for
                      well ordered and lattice-matched structures, the kinetics
                      involved in the growth processes drastically influences the
                      interface quality with a strong correlation to the magnetic
                      properties.},
