Significance Interfaces of transition-metal oxides (TMOs) offer a fertile platform to uncover emergent states, which has been extensively explored in 3 d TMOs with strong electron correlations. Recently research on 5 d TMOs with pronounced spin–orbit coupling (SOC) is flourishing due to the emergence of new topological states and potential application in spintronics. Interfaces between 3 d and 5 d TMOs provide a unique test bed to combine the merits of these two fundamental interactions. However, so far research is limited. Here we present results on one model system comprising the ferromagnet La 2/3 Sr 1/3 MnO 3 and the strong SOC paramagnet SrIrO 3 . We observe a manipulation of the magnetic anisotropy by tuning the SrIrO 3 dimensionality, which is accompanied by a novel SOC state in SrIrO 3 .
