Description

We present a study of the effect of lattice mismatch on the structure and magneto-transport properties of La{sub 0.67}Ca{sub 0.33}MnO{sub 3} (LCMO) epitaxial films. Pulsed laser deposition was used to synthesize epitaxial LCMO thin films on LaAlO{sub 3} (LAO), NdGaO{sub 3} (NGO), SrTiO{sub 3} (STO), and MgO substrates. Our results show that the nature of the lattice mismatch and the structure of the substrate governs the microstructure of the film. The microstructure consists of domains of two crystal structures, a pseudo-cubic phase and a monoclinic phase. The monoclinic phase forms as the film relaxes away from the interface, with an ... continued below

Description

We present a study of the effect of lattice mismatch on the structure and magneto-transport properties of La{sub 0.67}Ca{sub 0.33}MnO{sub 3} (LCMO) epitaxial films. Pulsed laser deposition was used to synthesize epitaxial LCMO thin films on LaAlO{sub 3} (LAO), NdGaO{sub 3} (NGO), SrTiO{sub 3} (STO), and MgO substrates. Our results show that the nature of the lattice mismatch and the structure of the substrate governs the microstructure of the film. The microstructure consists of domains of two crystal structures, a pseudo-cubic phase and a monoclinic phase. The monoclinic phase forms as the film relaxes away from the interface, with an orientation dependent on whether the film is under a tensile or compressive in-plane strain. A special case is observed on NGO where the orthorhombic nature of the substrate results in the alignment of the monoclinic phase so that its long axis is in the plane. The observation of an in-plane anisotropy in the magnetoresistance data for LCMO on NGO suggests that the monoclinic phase is important in explaining the magneto-transport properties.
