Magnetic structure of greigite (Fe3S4) probed by neutron powder diffraction and polarized neutron diffraction
[1] We have investigated greigite (Fe3S4) using a combination of neutron powder diffraction and polarized neutron diffraction to give the first unambiguous assignment of its magnetic structure. Our results confirm that greigite has a collinear ferrimagnetic structure with antiferromagnetic coupling between the tetrahedral (A) and octahedral (B) sites. Our analysis also indicates that greigite d...
متن کاملThe Fundamentals of Neutron Powder Diffraction
ii Certain commercial entities, equipment, or materials may be identified in this document in order to describe an experimental procedure or concept adequately. Such identification is not intended to imply recommendation or endorsement by the National Institute of Standards and Technology, nor is it intended to imply that the entities, materials, or equipment are necessarily the best available ...
متن کاملCrystal structure of (Li0.5K0.5)2C03 by neutron powder diffraction analysis
The crystal structure of (Li0.5K0.5)2C03 was determined by neutron powder diffraction. A final weighted R-factor of 4.54% was obtained for the refinement of 2373 reflections by the Rietveld method from a sample synthesized using 7Li2CO3 and K2CO3 (99.9% pure). Slight distortion of the CO$units in the monoclinic cell was observed; the O( 1)-C-0(2) angle and CO(3) length are larger than those for...
متن کاملIn situ powder neutron diffraction study of non-stoichiometric phase formation during the hydrogenation of Li3N.
The hydrogenation of Li3N at low chemical potential has been studied in situ by time-of-flight powder neutron diffraction and the formation of a non-stoichiometric Li4-2xNH phase and Li4NH observed. The results are interpreted in terms of a model for the reaction pathway involving the production of Li4NH and Li2NH, which subsequently react together to form Li4-2xNH. Possible mechanisms for the ...
متن کاملAn in situ Study of NiTi Powder Sintering Using Neutron Diffraction
This study investigates phase transformation and mechanical properties of porous NiTi alloys using two different powder compacts (i.e., Ni/Ti and Ni/TiH2) by a conventional press-and-sinter means. The compacted powder mixtures were sintered in vacuum at a final temperature of 1373 K. The phase evolution was performed by in situ neutron diffraction upon sintering and cooling. The predominant pha...
