description:
	We will use spatially-resolved, 3D x-ray microdiffraction (both white and monochromatic beams) to study phase separation and local microstructure in the directionally-solidified transition-metal oxide system, (Lu,LaSr)MnO.  We will measure the domain morphologies, lattice orientations, and local strain field fluctuations within the separate hexagonal LuMnO and rhombohedral LaSrMnO phases.  In particular, we will quantitatively map the reciprocal space positions and shapes of recently observed superlattice streaks.  We will attempt to understand how interactions between the domains can give rise to superlattice order.

	yes

z34ID_details:
	Parasitic operations in the other station will probably be difficult since we will need to change the undulator gap to optimize intensity for different reflections.
