The recent discovery of nanometer-size whirling magnetic structures named magnetic skyrmions has opened a new path to manipulate magnetization at the nanoscale [1,2]. Magnetic skyrmions are characterized by a chiral and topologically non-trivial spin structure, i.e their magnetization texture cannot be continuously transformed into the uniform magnetic state without causing a singularity (see Fig.1). Skyrmions can […] >>

The conversion of a conventional charge current into a spin current, carrying not charges but angular momentum, can be done in non-magnetic systems using the spin-orbit coupling. Spin-dependent transport effects can thus be observed in very wide ranges of materials and interfaces, allowing spin manipulation in metals, oxides [1], semiconductors, Rashba interfaces, topological insulators, 2D […] >>

Electron Holography is an advanced technique of Transmission Electron Microscopy that consists in reconstructing the full electron wave to access its phase. The phase of an electron wave is modulated by the presence of electro-magnetic fields that may be quantitatively mapped, once the phase is obtained. Beyond the possibility of describing magnetism (and more particularly […] >>

Magnetic non-volatile memory (MRAM) is a technology being developed at Spintec. This type of memory associates non-volatility with fast switching of the order of ns. Switching the magnetization direction the storage layer results in cell resistance changes that can be greater than 100%. This switching depends on the application of a current pulse and also […] >>

SUJET STAGE Master 2 ou Projet de Fin d’Etudes: A novel process to realize 4H-SiC nanowire arrays for biomedical applications The arrays of vertical nanopillars and nanowires (NW) are highly interesting for various applications. Such arrays are natural candidates for two-dimensional photonic crystals.In addition, the pitch between pillars could influence biological cell adhesion. A pillar […] >>
