description:
	We will use x-ray diffraction to study the temperature dependence of the in-plane and out-of plane lattice parameters, peak shapes and domain orientations for thin, epitaxial LaPrCaMnO films.  Different substrates (SrTiO, LaAlO, SrLaGaO, NdGaO) will be used to induce tensile, compressive or negligible in-plane stresses.  We expect that the in-plane strain will control the formation of domains associated with orthorhombic distortions of the MnO6 octraheda. We expect that the diffraction peaks will broaden at low temperatures due to the formation of nanoscale strain domains.  Results will be correlated with transport measurements and models of electronic phase domains.
