Magneto-acoustic coupling has proved an interesting approach to generate spin waves, the magnetic excitations that could encode information in new components. Until now, the role of magnetic hysteresis – i.e. the fact that the...
Converting magnetic excitation into electrical energy is of great interest for medical applications, such as remote implant charging. In a previous article, members of INSP showed that a Ni/LiNbO3/Ni composite produces a strong magnetoelectric...
X-ray photoemission spectroscopy (XPS) is a major technique in material science and nanoscience. Beyond its capability to identify elements and their chemical environments, it allows getting stoichiometries through core level peak areas. However, this...
Analysing nanoparticles with optical microscopy is a challenge: indeed, those nanoparticles are 10 times smaller than the theoretical resolution of any microscope, the diffraction limit. This limit is around 300 nm in our case....
Certain topological defects manifest as singularities or «nodes» in a phase field and are characterized by a winding number. A edge dislocation, is a typical example of such a defect, observed across a range...
Simulating quantum dynamics becomes increasingly challenging as the number of relevant degree of freedom grows. With MPSDynamics.jl, we present an open-source, user friendly Julia package designed to directly tackle this concern with the Matrix...
The morphological transition from disordered or irregular solidification microstructures to regular shapes in partially faceted eutectic alloys is an important phenomenon in the metallurgy of industrial alloys (e.g., aluminum-based). For a better understanding of...
Today, nanocrystals are establishing themselves as a versatile solution for the manufacture of next-generation of optoelectronic devices such as LEDs, photodetectors and photovoltaic cells. Recent work even suggests that ordered assemblies of nanoparticles, known...
Light can be confined within micro- or nanostructures, resulting in both resonance and energy localization. In cylindrical dielectric microstructures, resonant modes propagate along the circles bounding the cylinder: these are called whispering gallery modes....
Among various metal/semiconductor systems, copper/germanium alloys have been studied since the 1990s to understand the formation mechanisms of Schottky barriers, fundamental to diodes of the same name. This system, which felt into disuse, has...
