description:
	We will use x-ray diffraction to study the temperature dependence of the in-plane and out-of plane lattice parameters and peak shapes for thin, epitaxial LaPrCaMnO films.  Different substrates will be used to induce tensile, compressive or negligible in-plane stresses.  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.

equipment_required:
	Cryostat for low temperature measurements; Range ~20-300K

unacceptable_dates:
	January 29-31; March 4-16, 2008.  If both proposals get beamtime, I would prefer if possible that the 33BM (this proposal) film measurements are scheduled earlier in the run than the 34ID (microbeam) measurements.
