Abstract: Abstract:Oxide superlattices composed of ferromagnetic La0.7Ba0.3MnO3 (LBMO) and paramagnetic LaNiO3 (LNO) were grown on SrTiO3(001) substrates with dual-gun radio-frequency magnetron sputtering. The (00L) crystal-truncation-rod intensity profiles confirm the formation of a superlattice structure. The LBMO layer in the artificial superlattice structure is under biaxial compressive stress, whereas the LNO layer is under biaxial tensile stress. Experiments involving X-ray scattering, absorption, and atomic-force microscopy provide structural information about the designed superlattices. The observed Curie temperature of LBMO epi layers exhibits a strong correlation with lattice strain. All superlattices are coupled ferromagnetically at low temperature.
