Abstract

(La2/3-xYx) (Ca1/3-ySry)MnO3(LYCSMO) thin films withx = 0.08andy = 0.0868deposited onSrTiO3(STO), Yttrium-stabilizedZrO2(YSZ),LaAlO3(LAO), andMgOsubstrates are fabricated. Atomic force microscopy measurements reveal that the morphology is quite different for all films. A two-dimensional growth mode is suitable for LYCSMO film on STO, while on LAO, YSZ, andMgO, an island growth mode may be a good description for the growth of LYCSMO films. X-ray diffraction studies show that the films epitaxially grow alongcaxis on STO, LAO, andMgOsubstrates, while grows along a axis on YSZ substrate. The in-plane and out-of-plane lattice parameters are also obtained for films grown on all substrates.
