Crystal Growth in Fluid Flow: Nonlinear Response Effects
H. L. Peng, D. M. Herlach, Th. Voigtmann
We investigate crystal-growth kinetics in the presence of strong shear flow in the liquid, using molecular-dynamics simulations of a binary-alloy model. Close to the equilibrium me…
Experimental studies of crystal nucleation: metals and colloids
Diter M. Herlach, Thomas Palberg
Crystallization is one of the most important phase transformations of first order. In the case of metals and alloys, the liquid phase is the parent phase of materials production. T…
Equilibrium Fluid-Crystal Interfacial Free Energy of Bcc-Crystallizing Aqueous Suspensions of Polydisperse Charged Spheres
Thomas Palberg, Patrick Wette, Dieter M. Herlach
The interfacial free energy is a central quantity in crystallization from the meta-stable melt. In suspensions of charged colloidal spheres, nucleation and growth kinetics can be a…
Quasicrystal nucleation in an intermetallic glass-former
Wolfgang Hornfeck, Raphael Kobold, Matthias Kolbe +1
The discovery of quasicrystals 30 years ago challenged our understanding of order at the atomic scale. While quasicrystals possess long-range orientational order they lack translat…
Magnetic field distribution and characteristic fields of the vortex lattice for a clean superconducting niobium sample in an external field applied along a three-fold axis
A. Yaouanc, A. Maisuradze, N. Nakai +9
The field distribution in the vortex lattice of a pure niobium single crystal with an external field applied along a three-fold axis has been investigated by the transverse-field m…
Equilibrium interfacial free energies and Turnbull coefficient for bcc crystallizing colloidal charged sphere suspensions
Thomas Palberg, Patrick Wette, Dieter M. Herlach
We extend previous analysis of data for the melt-nucleus interfacial free energy, , gained from optical experiments on suspensions of charged colloidal spheres, which crystalliz…
Evidence for Cooper Pair Diffraction on the Vortex Lattice of Superconducting Niobium
A. Maisuradze, A. Yaouanc, R. Khasanov +6
We investigated the Abrikosov vortex lattice (VL) of a pure Niobium single crystal with the muon spin rotation (μSR) technique. Analysis of the μSR data in the framework of the BCS…
Complete description of re-entrant phase behaviour in a charge variable colloidal model system
Patrick Wette, Ina Klassen, Dirk Holland-Moritz +6
In titration experiments with NaOH we have determined the full phase diagram of charged colloidal spheres in dependence on the particle density n, the particle effective charge Zef…
Phase behaviour of deionized binary mixtures of charged colloidal spheres
Nina J Lorenz, Hans Joachim Schoepe, Holger Reiber +6
We review recent work on the phase behaviour of binary charged sphere mixtures as a function of particle concentration and composition. Both size ratios and charge ratios are varie…
