Coherent quasielastic neutron scattering and correlations between rotational jumps of molecules on a periodic lattice

G. Coddens

We previously derived a theorem about the {\em coherent} quasielastic neutron-scattering signal from a -dimensional lattice of molecules that are undergoing rotational jump…

Comment on "Atomic jumps in quasiperiodic AlNiCo and related crystalline material"

G. Coddens

We disagree with a number of statements by Dolinsek et al. about the specificity of phason dynamics in quasicrystals (QCs).

First order phase transition from the vortex liquid to an amorphous solid

M. Menghini, Yanina Fasano, F. de la Cruz +6

We present a systematic study of the topology of the vortex solid phase in superconducting BiSrCaCuO samples with low doses of columnar defects. A new state…

Vortex fluctuations in underdoped Bi2Sr2CaCu2O8+d crystals

S. Colson, M. Konczykowski, M. B. Gaifullin +5

Vortex thermal fluctuations in heavily underdoped Bi2Sr2CaCu2O8+d (Tc=69.4 K) are studied using Josephson plasma resonance (JPR). From the data in zero magnetic field, we obtain th…

First-order disorder-driven transition and inverse melting of the vortex lattice

Nurit Avraham, Boris Khaykovich, Yuri Myasoedov +9

Vortex matter phase transitions in the high-temperature superconductor Bi2Sr2CaCu2O8 were studied using local magnetization measurements combined with a vortex 'shaking' technique.…

Strong Pinning in High Temperature Superconductors

C. J. van der Beek, M. Konczykowski, A. Abaloshev +5

Detailed measurements of the critical current density jc of YBa2Cu3O7 films grown by pulsed laser deposition reveal the increase of jc as function of the filmthickness. Both this t…
