title = "Structural and magnetic properties of churchite-type REPO4·2H2O materials",
abstract = "The structural and magnetic properties of churchite-type REPO4·2H2O (RE = Gd to Lu) materials (low-temperature polymorph of the rare-earth phosphate family) are reported. The materials were synthesized at low temperatures (4 °C) using a precipitation method and the long-range and local structures were determined using powder XRD and XANES. The churchite materials crystallize in the monoclinic system (Space group – C2/c) and adopt a 2D layered structure with water occupying the interlayer regions. The churchite materials were found to transform to the xenotime structure at 300 °C. DC magnetization experiments reveal the absence of long-range magnetic ordering between 300 and 1.8 K. The effective magnetic moments (μeff) are similar to those of the free RE (RE = Gd, Tb, Dy, Ho, Er) ions.",

The P L2,3-edge XANES spectra was collected at the VLS-PGM beamline (1ID-2), Canadian Light Source, a national research facility of the University of Saskatchewan, which is supported by the Canada Foundation for Innovation (CFI), the Natural Sciences and Engineering Research Council (NSERC), the National Research Council (NRC), the Canadian Institutes of Health Research (CIHR), the Government of Saskatchewan, and the University of Saskatchewan. The Lu L1-edge XANES spectra was collected at the 20 BM beamline (CLS@APS Sector 20, APS). Sector 20 facilities at the Advanced Photon Source, and research at these facilities, are supported by the U.S. Department of Energy - Basic Energy Sciences, the Canadian Light Source and its funding partners, and the Advanced Photon Source. Use of the Advanced Photon Source, an Office of Science User Facility operated for the U.S. Department of Energy (DOE) Office of Science by Argonne National Laboratory, was supported by the U.S. DOE under Contract No. DE-AC02-06CH11357. The beamline staff at the VLS-PGM beamlines in CLS and the Sector 20 BM beamlines at the APS are thanked for their support during beamtime. M. R.
