  Crystal structure and complex magnetic behaviour of a novel uranium oxyphosphide UCuPO

  摘要：

  The crystal structure of UCuPO was determined from single-crystal X-ray data and refined to a residual of R = 0.033 for 192 structure factors and 12 variables. It has a tetragonal ZrCuSiAs-type structure: P4/nmm, a = 379.3(1) pm, c = 823.3(2) pm, Z = 2. Magnetisation and magnetic susceptibility measurements of a powder sample in the range 5-300 K show UCuPO to order antiferromagnetically at T-N = 220+/-2 K. Its chi(T) dependence appears to be highly anomalous with a strong upturn at low temperatures. The close relationship between UCuPO and U2Cu2P3O with respect to their crystal structures and their magnetic behaviour is discussed.

  Near-surface effects at the antiferromagnetic phase transition in uranium phosphide

  摘要：

  A careful investigation of the resonant x-ray magnetic-scattering response in uranium monophosphide reveals the crucial role played by magnetization density correlations in the discontinuous paramagnetic to antiferromagnetic phase transition in this material. The magnetization density correlations, which are measured on the short time scale typical of the resonant x-ray-scattering technique, appear highly anisotropic in their inferred spatial distribution. Such correlated regions exist in the near-surface regime probed by the low-energy x-ray beam (3.278 keV) and exhibit strongly temperature-dependent behavior at and above the bulk phase transition. For specular reflections this leads to well defined two length scale diffraction profiles in the vicinity of the phase transition and, when taken with the off-specular data, to a phenomenological model which suggests that the extended length scale of near-surface antiferromagnetism may arise from a localized surface distortion. This type of model may be more generally useful both in the two length scale problem and in other systems where defects or fluctuations may, in a similar manner, drive pseudo-long-range order.

It has been suggested that the magnetically ordering behavior such as the direction of the moments would be closely correlated with the band structure.
