A series of table-top dilution cryostats has been realized at the Néel Institute. These cryostats, which are highly appreciated by our experimentalists, make it possible to reach temperatures of about 30 mK in only 3 hours. Full text

The continuing decrease of the size of the structures used in semiconductor electronics and in magnetic information storage devices has dramatically reduced the number of atoms necessary to process and store one bit of information ... Full text

For more than a decade already and because of their technological potential for incorporation in spintronic devices, diluted magnetic semiconductors (dmS’s) have attracted a considerable attention from both experimentalists and theoreticians. Full text

Single-electron circuitry is a promising route for processing quantum information, but it requires a mechanism to transport single electrons from one functional part of the circuit to another. Full text

Parametric amplification is an extremely useful scheme applied in optics, electronics and also mechanics. Full text

Hybrid pixel detectors will mark the end of the era of ccd cameras in numerous experiments using x-rays. the ”xpad” technology, born of a collaboration involving the néel institute, is one example of such a detector.  Full text

Stirring a honey pot with a spoon is awkward because the fluid viscosity damps the flow very ef- ficiently. Full text

Diamond is a ”wide bandgap” semiconductor : eG=5.4 eV, five times larger than that of silicon. It is considered as the ultimate material for fast, high voltage and high power electronics. Full text

Superconductivity is due to the condensation of a fraction of the electrons into cooper pairs. Full text

In tumor biology, imaging of new blood vessel growth (angiogenesis) associated with a tumor during its development ... More

We have measured the phase matching directions for second harmonic generation and dif- ference-frequency generation in the nonlinear crystal cdSip2 , at infrared wavelengths up to 9.5 μm. Full text

The intense experimental efforts of several groups worldwide during the last six years have very recently culminated by demonstrating what the scientific community considered unrealistic only 10 years ago : cooling a macros- copic mechanical oscillator down to its quantum ground state of motion. Full text

following the discovery of x-rays by roentgen, W. H. bragg and W. l. bragg used these waves to perform diffraction experiments on crystals and to determine the atomic positions within their ordered structures. Full text

Magnetic thin films and multilayers are investigated both for their fundamental magnetic properties and for spintronics (the coupling of magnetism with electronic transport). Full text

Flexural hinges are used more and more in microsystem technology. Full text

Insulating granular aluminium films are experimental realizations of disordered insulators. Full text

Quantum mechanics was developed initially to describe properties of electrons in atoms which could not be explained by the classical laws of physics. Full text

This project will explore quantum mechanical coherence in Josephson crystals and apply it for frequency to-current conversion. Full text

This project concerns the field of coherent, nonlinear, ultrafast, light matter interaction on a quantum level in solids. Full text

In quantum nanoelectronics, a major goal is to use quantum mechanics in order to build efficient nanoprocessors. Full text

It has recently become possible to cool macroscopic mechanical oscillators down to their quantum ground state of motion. Full text
