Pulsed laser deposition of highly textured La5Ca9Cu24O41 films on SrLaAlO4 (1Â 0Â 0) and Gd3Ga5O12 (1Â 0Â 0) substrates

► Growth of highly b-axis oriented LCCO films on SrLaAlO4 (1 0 0) and Gd3Ga5O12 (1 0 0) substrates. ► The grain size depends strongly on the substrate temperature and the oxygen pressure. ► Purely b-axis oriented LCCO films were deposited on Gd3Ga5O12 single crystals using PO2=20Pa and Tsub = 850 °C.
