Abstract

Residual stresses and texture in La 2/3Sr 1/3MnO 3 (LSMO) thin films have been investigated. The films were deposited on (100) LaAlO 3 (LAO) and (100) MgO single crystals by liquid delivery-metal organic chemical vapor deposition (LD-MOCVD). X-ray diffraction (XRD) pole figures showed (001) LSMO//(001) LAO and (001) LSMO//(001) MgO preferred orientation. Residual stresses were calculated using a modified sin 2ψ method, crystallite group method (CGM), assuming a biaxial stress state. Compressive stresses on the order of 224 and 1150MPa were obtained for LSMO films deposited on LAO (LSMO/LAO) and MgO (LSMO/MgO), respectively.
