  Bilayers of the oxide 3d ferromagnet La$_{0.7}$Sr$_{0.3}$MnO$_{3}$ (LSMO) and
the 5d paramagnet SrIrO$_{3}$ (SIO) with large spin-orbit coupling (SOC) have
been investigated regarding the impact of interfacial SOC on magnetic order.
For the growth sequence of LSMO on SIO, ferromagnetism is strongly altered and
large out-of-plane-canted anisotropy associated with lacking magnetic
saturation up to 4 T has been observed. Thin bilayer films have been grown
coherently in both growth sequences on SrTiO$_3$ (001) by pulsed laser
deposition and structurally characterized by scanning transmission electron
microscopy (STEM) and x-ray diffraction (XRD). Measurements of magnetization
and field-dependent Mn L$_{2,3}$ edge x-ray magnetic circular dichroism (XMCD)
reveal changes of LSMO magnetic order which are strong in LSMO on SIO and weak
in LSMO underneath of SIO. We attribute the impact of the growth sequence to
the interfacial lattice structure/symmetry which is known to influence the
interfacial magnetic coupling.
