Journal ArticleDOI
Recent advances in magnetic structure determination by neutron powder diffraction
TL;DR: In this article, the main formulas governing the analysis of the Bragg magnetic scattering are summarized and shortly discussed and the method of profile fitting without a structural model to get precise integrated intensities and refine the propagation vector(s) of the magnetic structure is discussed.
Journal ArticleDOI
Neutron-diffraction study of the Jahn-Teller transition in stoichiometric LaMnO 3
TL;DR: The parent compound of the giant magnetoresistance Mn-perovskite has been studied by thermal analysis and high-resolution neutron-powder diffraction as discussed by the authors, which is characterized by an antiferrodistorsive orbital ordering due to the Jahn-Teller effect.
Journal ArticleDOI
Neutron diffraction study on structural and magnetic properties of La2NiO4
TL;DR: An overall survey of the structural and magnetic features of the La2NiO4+ delta system is presented as a result of neutron diffraction experiments in this article, where a tentative phase diagram is proposed.
Journal ArticleDOI
Magnetic Structures of the Triphylite LiFePO4 and of Its Delithiated Form FePO4
TL;DR: In this paper, the magnetic structures of LiFePO4 and its delithiated form FePO4 (triphylite, olivine group, space group Pnma) were solved using neutron diffraction on polycrystalline samples.
Journal ArticleDOI
Electronic Crystallization in a Lithium Battery Material: Columnar Ordering of Electrons and Holes in the Spinel LiMn 2 O 4
TL;DR: In this paper, the authors solved the structure at 230 K and deciphered unambiguously the nature of phase transition in rechargeable Li batteries, and showed that the transition results from a partial charge ordering, accompanied by simultaneous orbital ordering due to the Jahn-Teller effect.
