Ordered interfaces for dual easy axes in liquid crystals
Emmanuelle Lacaze, A Apicella, M De Santo +4
Using nCB films adsorbed on MoS 2 substrates studied by x-ray diffraction, optical microscopy and Scanning Tunneling Microscopy, we demonstrate that ordered interfaces with well-de…
Critical Scattering and Dynamical Scaling in an Heisenberg Ferromagnet Neutron Spin Echo versus Renormalization Group Theory
Michel Alba, Stephanie Pouget, Peter Fouquet +2
High resolution Neutron Spin Echo (NSE) spectroscopy was used to investigate the dynamics of an 3D Heisenberg ferromagnet in the exchange-controlled regime over a broad range of te…
Structure of smectic defect cores: an X-ray study of 8CB liquid crystal ultra-thin films
Jean-Philippe Michel, Emmanuelle Lacaze, Michel Goldmann +3
We study the structure of very thin liquid crystal films frustrated by antagonistic anchorings in the smectic phase. In a cylindrical geometry, the structure is dominated by the de…
Aging, rejuvenation and memory effects in re-entrant ferromagnets
V. Dupuis, E. Vincent, M. Alba +1
We have studied the slow dynamics of the ferromagnetic phases of the re-entrant CdCr_{2x}In_{2-2x}S_4 system for 0.85<x<=1 by means of low frequency ac susceptibility and magnetiza…
Dynamic critical behavior of disordered 3D Heisenberg ferromagnets
M. Alba, S. Pouget
The influence of a strong disorder on the critical dynamics of 3D Heisenberg ferromagnet was investigated by high-resolution quasielastic neutron scattering. A new disorder-induced…
Pairing evidence of 8CB molecules adsorbed on MoS2: Influence of 2D commensurability on the intralamellar structure
E. Lacaze, M. Alba, M. Goldmann +2
By combining X-ray diffraction studies under grazing incidence (GIXD) and Scanning Tunneling Microscopy (STM) measurements, we have precisely determined the structure of 8CB molecu…
