Lithium ion batteries (LIB) are considered as prime candidates for electric vehicles. Among them, batteries with silicon nanoparticles (SiNPs) based negative electrode are very promising, thanks to their important energy storage capacity, ten times higher than the current ones. But their low ... More »

Electron pumps are devices delivering a quantized current when driven at a frequency f: I=Nef, where N is an integer and e the electron charge. Electron pumps capable of delivering a current higher than 100 pA (corresponding to f >600MHz) with sufficient accuracy are likely to become the direct ... More »

In the 1990 years several groups tried to design purely organic polymers with collective magnetic properties (ideally with a ferromagnetic transition). The best result in this field was reported in 2001 by Rajca et al, who obtained a high-spin (S~5000) polymer exhibiting some of the properties of ... More »

Spintronics applications use ferromagnetic(F)/antiferromagnetic(AF) exchange bias (EB) interactions to set the reference direction required for the spin of conduction electrons. They therefore may involve layers intermixing originating from F/AF interfaces. As a consequence of intermixing, ... More »

Usually, magnetic tunnel junctions consist of electrodes made of an alloy of cobalt, iron and boron (CoFeB) and a tunnel barrier in magnesium oxide (MgO). To bring perpendicular anisotropy to such structures, multilayers of cobalt and platinum (Co/Pt) may be used. However, it is necessary to ... More »
