“…Powder and single-crystal neutron diffraction experiments on La 0.25 Pr 0.75 Co 2 P 2 were carried out using the HB-2A high-resolution powder diffractometer [18] and the HB-3A four-circle diffractometer [19] at the High Flux Isotope Reactor at Oak Ridge National Laboratory. For the powder diffraction measurements we employed 1.536 Å and 2.410 Å neutron wavelengths that were produced by (115) and (113) reflections, respectively, from a vertically focusing Ge monochromator.…”

Incommensurate crystal supercell and polarization flop observed in the magnetoelectric ilmeniteMnTiO3

“…Powder neutron diffraction was carried out on the HB-2A diffractometer at the High Flux Isotope Reactor (HFIR, Oak Ridge, TN). [24] For each experiment on the stoichiometric and Fesample, five grams of sample were loaded into vanadium cans. Diffraction patterns were collected at both 300 K and 10 K using a wavelength of 1.54 Å.…”

“…To determine the magnetic structure, separate NPD measurements were performed using a 6 g sample on HB-2A at the High Flux Isotope Reactor at ORNL [26]. The sample was sealed in a vanadium can with He exchange gas, and a closed cycle refrigerator was used to reach 3.5 K. Measurements were conducted with a neutron wavelength of 2.4137 Å, with collimation of 12 -open-12 .…”
