Group’s recent work has been dedicated to the growth, structural and physical properties investigations of superlattices combining ferromagnetic and ferroelectric oxides, such as, all-ferromagnetic La_0.7Sr_0.3MnO₃ / SrRuO₃ with antiferromagnetic interlayer coupling and La_0.7Sr_0.3MnO₃ / BaTiO₃/ SrRuO₃ superlattices.

Z-contrast STEM micrograph (TITAN 80-300, Dr. E. Pippel) of a ferromagnetic / ferroelectric / metallic superlattice consisting of La_0.7Sr_0.3MnO₃ / BaTiO₃ /SrRuO₃, grown on SrTiO₃(100) in the new Minerva PLD machine.
