Anharmonic Thermal Motion in the 93-K Superconductor Ba2YCu3O7 Using Multiple-Wavelength X-Ray Diffraction
We have obtained anisotropic thermal parameters for Ba2YCu3O7 from a dual-wavelength x-ray crystal structure determination on a single crystal with a small amount of twinning. Anharmonic thermal motion was found for both Ba and Cu atoms with the largest anharmonic feature attributed to a Ba-Ba breathing mode. The anisotropic and anharmonic thermal parameters are consistent with the coordination polyhedra as well as the bonding distances involved.
