3 Neutrons & x-rays: similar methods, sensitive to different elements.

We used a recently developed large-area single-crystal flatplate sample holder [4] to place about 1.6 g of material in the neutron beam. The scattering measurements were carried out at a wavelength of Å on the D20 thermal powder diffractometer at the ILL. For each sample, data sets were obtained at 1.6 K and 10.0 K with counting times of 10 hours (SmFeAsO) and 15 hours (SmFeAsO February( F 0.15 ) for each temperature. The purely nuclear patterns at 10 K (figure 1a) were fitted to establish scale factors, lattice parameters and the instrument profile function. These were then fixed while the difference patterns (1.6 K 10 K) were fitted to obtain the magnetic structure. All refinements of the neutron diffraction patterns employed the FullProf suite [5, 6]. High-intensity two-axis diffractometer D20 The samarium moments were found to order antiferromagnetically along the c axis in a G-mode which has a + + moment sequence. This structure corresponds to the Cm'm'a' group. Figure 2a shows a representation of the derived magnetic structure of SmFeAsO at a1.6 K. Fitting the section of the diffraction pattern shown in figure 1b E. Ressouche - Ecole Neutrons et magnétisme yields a samarium JDN moment 20 (18 of (3) mai 2012) µ B for SmFeAsO at 1.6 K. A similar analysis of the SmFeAsO 0.85 F 0.15 data shown in figure 1d yields a closely related magnetic structure (Shubnikov magnetic space group: P4/n'm'm') and a Sm moment of 0.53(3) µ B. The most significant aspect of the pattern shown in figure 1d is not that SmFeAsO and SmFeAsO 0.85 F 0.15 adopt closely related magnetic structures, but rather, that the samarium moments are a b c a b February(2014 b a MAGNETISM SCIENTIFIC HIGHLIGHTS Magnetic moment Particle Neutral Diffractometers - Measure structures Where atoms and molecules are Spectrometers - Measure dynamics What atoms and molecules do High-intensity two-axis diffractometer D20 Figure 2: (a) The samarium magnetic structure of SmFeAsO at 1.6 K.
