Surface conductivity of DR1-functionalized organic-inorganic sol-gel materials
J. -A. Reyes-Esqueda, A. Franco, M. Bizarro +7
In recent years, in looking for an important photorefractive application, several studies on electro-optic and photoconductive sol-gel responses have been done. A very important ef…
Effect of chromophore-chromophore electrostatic interactions in the NLO response of functionalized organic-inorganic sol-gel materials
J. Reyes-Esqueda, B. Darracq, J. Garcia-Macedo +7
In the last years, important non-linear optical results on sol-gel and polymeric materials have been reported, with values comparable to those found in crystals. These new material…
Optical 3D-storage in sol-gel materials with a reading by Optical Coherence Tomography-technique
Jorge-Alejandro Reyes-Esqueda, Laurent Vabre, Romain Lecaque +11
We report on the recording of 3D optical memories in sol-gel materials by using a non-linear absorption effect. This effect induces a local change of the optical properties of the…
A new experimental procedure for characterizing quantum effects in small magnetic particle systems
R. Sappey, E. Vincent, M. Ocio +4
A new experimental procedure is discussed, which aims at separating thermal from quantum behavior independently of the energy barrier distribution in small particle systems. Magnet…
Anomalies in the Relaxation of Small Magnetic Particles at Very Low Temperatures
R. Sappey, E. Vincent, J. Hammann +3
The magnetization relaxation rate of small gamma-Fe2O3 particles dispersed in a silica matrix has been measured from 60 mK to 5 K. It shows a minimum around 150 mK, that can be dis…
