description:
	Using 3D Laue microdiffraction, we will investigate the local microstructural and strain inhomogeneities in self-organized, phase-separated domains in the manganite systems (LaSrLu)MnO3 and (Eu,Y)MnO3.  We will use microfluorescence to map the composition of domains and 3D microdiffraction to map the spatial variations in phase, orientation, and lattice strain. We will use energy-wire-position scans to measure the absolute lattice parameter changes near phase boundaries and fluctuations within individual lamella.  We will compare structural measurements with electronic (photoemission) observations, and interpret the results in terms of theoretical models for phase coexistence.

z34ID_details:
	Most (>80-90%) of these 34ID-E diffraction measurements can be made with off-axis beam and undulator ~8-9 keV. However, some on-axis fluorescence measurements will also be required.
