The high specific surface of porous silicon and its high reactivity makes this material a good candidate for chemical sensors based on electrical or electromechanical devices. In this paper, several processes are presented to realize free-standing po

The electromagnetic field distribution on an illuminated rough gold surface has been investigated by apertureless scanning near-field optical microscopy. The sample consists of an alumina substrate with a variable gold coverage ranging from 0 to 30 m

Inductors are basic components of magnetic sensors. Generally, with those sensors, a weak magnetic variation has to be detected. As the sensitivity increases with the inductance value, our objectives are to design inductors with a maximum of turns wh

In this paper, we present our work aiming to explore the nano-structuring potential of high resolution focused ion beams (FIB), a technology capable of overcoming some basic limitations of current nano-fabrication techniques and to propose new patter

Controlled and reproducible fabrication of nano-structured materials will be one of the main industrial challenges in the next few years. We have recently proposed exploitation of the nano-structuring potential of a high resolution Focused Ion Beam T

The appearance of well-defined steps on vicinal Si (111) surfaces has a very pronounced effect on the rotational anisotropy of the Second Harmonic Generation (SHG) from these surfaces. This effect is related to the lowering of the surface symmetry an

The domain structure and magnetisation reversal phenomenon in ultrathin magnetic film structures with perpendicular anisotropy are reviewed. The domain wall motion is studied in virgin and He ion irradiated Pt/Co(0.5nm)/Pt films. The field (H) depend

The dependence of the magnetic anisotropy, magnetization reversal processes and magnetic domain patterns in Pt/Co(h)/Pt(1 1 1) ultra-thin ferromagnetic films have been studied, as a function of the Co layer thickness d (0.5⩽d⩽3 nm), by magneto-op

The magnetic properties of Pt/Co/Pt sandwiches prepared by sputtering onto Al 2 O 3 (0 0 0 1) single crystal substrates have been investigated in relation with their structure. Co island coalescence is completed before deposition of 40 A of Pt. The s

Extraordinary Hall effect was used to detect the propagation of a coherent 1D Bloch-like domain wall (DW) in submicron structures based on Pt/Co( t Co =1 nm)/Pt sandwiches. We found that the device geometry such as its shape and its size strongly aff
