Wave vector dependence of the dynamics in supercooled metallic liquids
B. Ruta, S. Hechler, N. Neuber +13
We present a detailed investigation of the wave vector dependence of collective atomic motion in Au49Cu26.9Si16.3Ag5.5Pd2.3 and Pd42.5Cu27Ni9.5P21 supercooled liquids close to the…
Activation energy spectrum for relaxation and polyamorphism in an ultra-viscous metallic glass former
Isabella Gallino, Daniele Cangialosi, Zach Evenson +4
Many glass-formers exhibit phase transitions between two distinct liquid states. For some metallic glass-formers, the liquid-liquid transition is experimentally found in the superc…
Controlling the dynamics of a bidimensional gel above and below its percolation transition
D. Orsi, B. Ruta, Y. Chushkin +5
The morphology and the microscopic internal dynamics of a bidimensional gel formed by spontaneous aggregation of gold nanoparticles confined at the water surface are investigated b…
Compressed correlation functions and fast aging dynamics in metallic glasses
B. Ruta, G. Baldi, G. Monaco +1
We present x-ray photon correlation spectroscopy measurements of the atomic dynamics in a Zr67Ni33 metallic glass, well below its glass transition temperature. We find that the dec…
Atomic-scale relaxation dynamics and aging in a metallic glass probed by X-ray photon correlation spectroscopy
B. Ruta, Y. Chushkin, G. Monaco +5
We use X-Ray Photon Correlation Spectroscopy to investigate the structural relaxation process in a metallic glass on the atomic length scale. We report evidence for a dynamical cro…
