One Dimensional(1D)-to-2D Crossover of Spin Correlations in the 3D Magnet ZnMn 2 O 4

December 8, 2015
Author(s)
Steven M.T. Disseler, Ying Chen, S. Yeo, G. Gasparovic, P.M.B. Piccoli, A. J. Schultz, Yiming Qiu, Qingzhen Huang, S.-W. Cheong, William D. Ratcliff
We report on the intriguing evolution of the dynamical spin correlations of the frustrated spinel ZnMn 2O 4. Inelastic neutron scattering and magnetization studies reveal that the dynamical correlations at high temperatures are 1D. At lower temperature

Slow and static spin correlations in Dy 2+h Ti 2-hO d7-d

April 17, 2011
Author(s)
Jason S. Gardner, G. Ehlers, P. Fouquet, B. Farago, J. R. Stewart
The static and dynamic spin correlations in the spin-ices Dy 2.3Ti 1.7O 6.85 and Dy 2Ti 2O 7 have been studied in polarised neutron diffraction and neutron spin echo experiments. The measurements reveal that, below 100 mK, the magnetic scattering broadens

Structures of Biological Minerals in Dental Research

December 1, 2001
Author(s)
M Mathew, Shozo Takagi
Structural features of some calcium phosphates of biological interest are described. Structure of hydroxyapatite (OHAp), considered as the prototype for the inorganic component of bones and teeth is discussed with respect to the kinds and locations of

Critically Evaluated Atomic Transition Probabilities for Sulfur S I Through S XV

November 14, 2018
Author(s)
Larissa Podobedova, Daniel E. Kelleher, Wolfgang L. Wiese
Atomic transition probabilities for about 6700 allowed and forbidden lines of S I through S XV are tabulated, based on a critical evaluation of recent literature sources. The transition probabilities were obtained mainly from recent sophisticated
