Quasi-Elastic Scattering, Random Fields and phonon-coupling effects in PbMg1/3Nb2/3O3
S N Gvasaliya, B Roessli, R A Cowley +2
The low-energy part of the vibration spectrum in PbMgNbO (PMN) relaxor ferroelectric has been studied by neutron scattering above and below the Burns temperatur…
Pairing Interactions and Gibbs Adsorption at the Liquid Bi-In Surface: A Resonant X-Ray Reflectivity Study
Elaine DiMasi, Holger Tostmann, Oleg G. Shpyrko +5
Resonant x-ray reflectivity measurements from the surface of liquid Bi22In78 find only a modest surface Bi enhancement, with 35 atomic % Bi in the first atomic layer. This is in co…
Microscopic View on Short-Range Wetting at the Free Surface of the Binary Metallic Liquid Gallium-Bismuth: An X-ray Reflectivity and Square Gradient Theory Study
Patrick Huber, Oleg Shpyrko, Peter S. Pershan +3
We present an x-ray reflectivity study of wetting at the free surface of the binary liquid metal gallium-bismuth (Ga-Bi) in the region where the bulk phase separates into Bi-rich a…
Wetting behavior at the free surface of a liquid gallium-bismuth alloy: An X-ray reflectivity study close to the bulk monotectic point
Patrick Huber, Oleg Shpyrko, Peter S. Pershan +4
We present x-ray reflectivity measurements from the free surface of a liquid gallium-bismuth alloy (Ga-Bi) in the temperature range close to the bulk monotectic temperature $T_{mon…
X-ray study of the liquid potassium surface: structure and capillary wave excitations
Oleg Shpyrko, Patrick Huber, Peter S. Pershan +4
We present x-ray reflectivity and diffuse scattering measurements from the liquid surface of pure potassium. They strongly suggest the existence of atomic layering at the free surf…
