Perovskite oxides, when combined into heterostructures and superlattices can yield emergent properties not present in the constituent components. Here, by combining LaNiO3, a Pauli paramagnetic material, with LaFeO3, an antiferromagnetic insulator, Zhou et al create a strongly ferromagnetic superlattice with a Curie temperature of over 600 K.
