International audience; KBiFe 2 O 5 (KBFO) was grown by pulsed laser deposition (PLD) on SrTiO 3 (001) (STO), 1 at% Nb-SrTiO 3 (001) (Nb-STO) and MgAl 2 O 4 (001) (MAO). In the case of MAO substrate, epitaxial growth is obtained. As its bandgap is re

We investigate the nonlinear absorption of C60-doped porous sol-gel glasses by single- and double-pulse pump–probe experiments. We find that the reverse saturable absorption (RSA) of these samples can be explained in the frame of a five level syste

The first example of anion doped high Tc material Nd2CuO4−xFx was recently discovered by James, Zahurak et al. In order to increase the amount of superconducting material we used new preparation routes. A two step process was used: preparation of T
