Work in the Kanatzidis group was supported by the Office of Naval Research. Work in the Spaldin group was supported by the NSF under award DMR-0940420. The neutron diffraction measurements were carried out at the Lujan Center at Los Alamos National Laboratory, and the x-ray experiments were carried out at the Advanced Photon Source, Argonne National Laboratory, both of which are supported by DOE-BES, and the calculations were performed at the San Diego Supercomputer Center, which is supported by NSF.
