Décès de Massimo Marezio

C’est avec une grande tristesse que nous avons appris le décès de Massimo Marezio, le 13 mai 2019 dans sa ville natale de Rome. Il nous laisse le souvenir d’un homme de grande gentillesse, à l’écoute de chacun, faisant preuve d’une large ouverture d’esprit et qui a su insuffler des idées nouvelles. La suite ici

Visite de l’équipe internationale d’Air Liquide

A l’occasion de la tenue de son séminaire annuel à Grenoble (avril 2019), Air Liquide international souhaitait montrer à son personnel technique, logistique et administratif, ainsi qu’aux différents directeurs de l’entreprise Air Liquide, comment et à quoi est utilisé l’hélium en particulier dans nos laboratoires de recherche.

Ultrasensitive and universal vectorial force-field sensor

Due to their ultralow mass, nanometre-scale mechanical oscillators can be used to convert a very weak force into a measurable displacement. By measuring the vibrations of a long, cylindrical, nanowire oscillator, and recording their modifications as the nanowire is scanned through a force field (e.g. an electrostatic field), one can measure and map the variations of the magnitude and direction of the force field with attonewton (10-18 N) precision. Lateral force-field gradients couple the nanowire’s two transverse eigenmodes, i.e. the transverse modes of oscillation in two perpendicular directions, causing frequency shifts and rotation of the eigenmode basis.

Scanning Hall-Probe Microscopy

At the Institut NEEL, we develop many highly sophisticated scanning probes to use for a large variety of experiments under extreme conditions of magnetic field, low temperature and vacuum, as well as microscopes sensitive to charge, to currents, to magnetic fields, forces, electrical potential, to name just a few. Here, we wish to highlight a microscope which does not operate under extreme conditions but has the advantage of being extremely versatile. This microscope is a "Scanning Hall-Probe Microscope" (SHPM) which allows us to do direct, quantitative measurements of the spatial variation of a a magnetic field, that is to "map" the field.
