Ferromagnetic order controlled by the magnetic interface of LaNiO₃/La_2/3Ca_1/3MnO₃ superlattices.

ABSTRACT: Interface engineering in complex oxide superlattices is a growing field, enabling manipulation of the exceptional properties of these materials, and also providing access to new phases and emergent physical phenomena. Here we demonstrate how interfacial interactions can induce a complex charge and spin structure in a bulk paramagnetic material. We investigate a superlattice (SLs) consisting of paramagnetic LaNiO₃ (LNO) and highly spin-polarized ferromagnetic La_2/3Ca_1/3MnO₃ (LCMO), grown on SrTiO₃ (001) substrate. We observed emerging magnetism in LNO through an exchange bias mechanism at the interfaces in X-ray resonant magnetic reflectivity. We find non-symmetric interface induced magnetization profiles in LNO and LCMO which we relate
