Electrical and magnetic properties of cuprate-manganate multilayers grown by metalorganic aerosol deposition — •Philipp Busse, Florian Fischgrabe, Sebastian Hühn, Markus Jungbauer, Markus Michelmann, and Vasily Moshnyaga — I. Physikalisches Institut, Universität Göttingen, Germany

Multilayers of superconducting cuprates and ferromagnetic manganates reveal interesting effects like spin injection, proximity effects, giant magnetoresistance and interlayer magnetic coupling [1], [2]. The growth of cuprate layers by metalorganic aerosol deposition (MAD) was studied for different deposition parameters (temperature, deposition rate and precursor molarity) and the used substrates (Al2O3, MgO and SrTiO3). Epitaxial growth of La2-xSrxCuO4 (LSCO) on SrTiO3 (100) substrates was evidenced by global (x-ray diffraction) and local (STM) structural characterization. A magnetic coupling between LCO and La0.7Sr0.3MnO3 (LSMO) was indicated by an increase of coercive field of ferromagnetic LSMO in the LSMO/LCO bilayer. Acknowledgment goes to the SFB 1073-B04 for support.
