Journal ArticleDOI
Structural effects on the magnetic and transport properties of perovskite A 1-x A' x MnO 3 (x=0.25, 0.30)
Paolo G. Radaelli,G. Iannone,M. Marezio,Harold Y. Hwang,Sang-Wook Cheong,James D. Jorgensen,Dimitri N. Argyriou +6 more
TL;DR: In this article, the evolution of the structural properties of the metal-insulator transition was determined as a function of temperature, average $A$-site radius and applied pressure for the ''optimal'' doping range $x=0.25,$ 0.30, by using high-resolution neutron powder diffraction.
Journal ArticleDOI
Charge, orbital, and magnetic ordering in La 0.5 Ca 0.5 MnO 3 s
TL;DR: In this article, an analysis of synchrotron x-ray and neutron powder diffraction data indicates that the anomalous and hysteretic behavior of the lattice parameters occurring between 225 K and 155 K is due to the development of a Jahn-Teller distortion of the octahedra, the orbitals being oriented perpendicular to the orthorhombic b axis.
Journal ArticleDOI
Simultaneous structural, magnetic, and electronic transitions in La1-xCaxMnO3 with x=0.25 and 0.50.
Paolo G. Radaelli,David E. Cox,M. Marezio,M. Marezio,S.-W. Cheong,Peter Schiffer,Arthur P. Ramirez +6 more
TL;DR: The ferromagnetic transition for {ital x}=0.50 is accompanied by an unusual peak broadening terminating at {ital T}{sub {ital N}}, and this newly observed behavior can be explained assuming that multiple intermediate phases are simultaneously present in the sample.
Journal ArticleDOI
Spin Waves and Revised Crystal Structure of Honeycomb Iridate Na2IrO3
Sungkyun Choi,Radu Coldea,Aleksey N. Kolmogorov,Tom Lancaster,Igor Mazin,Stephen J. Blundell,Paolo G. Radaelli,Yogesh Singh,Yogesh Singh,Philipp Gegenwart,K. R. Choi,S-W. Cheong,S-W. Cheong,Peter J. Baker,Chris Stock,J W Taylor +15 more
TL;DR: Combining single-crystal diffraction and density functional calculations, a revised crystal structure model with significant departures from the ideal 90° Ir-O-Ir bonds required for dominant Kitaev exchange is proposed.
Journal ArticleDOI
Structural phenomena associated with the spin-state transition in LaCoO 3
TL;DR: In this article, high-resolution neutron powder diffraction in the temperature range $5l~Tl~1000\mathrm{K] was used to study the structural properties of the LaCoO+3 lattice.
