On Thursday October 24th 2024, we have the pleasure to welcome in SPINTEC Anjan SOUMYANARAYANAN Assistant professor at the National University of Singapore (NUS). He will give us a seminar at 11:00 entitled : Decoding Electrical Signatures of Chiral Spin Textures Place : IRIG/SPINTEC, auditorium 445 CEA Building 10.05 (access to CEA requires an entry […]

We propose the concept of a core-shell composite structure coupled antiparallel via dipolar interaction, as the storage layer in perpendicular-shape-anisotropy magnetic random access memory (PSA MRAM). Benefits compared with a standard PSA MRAM include a reduced write time and the stray field. CoFeB core with a Co shell (height 8 nm; diameters 14 and 20 […]

On Thursday October 26th 2023, we have the pleasure to welcome in SPINTEC Claire Donnelly from Max Planck Institute for Chemical Physics of Solids, Dresden, Germany and guest Professor at UGA for one month. She will give us a seminar at 10:00 entitled : Mapping and controlling three dimensional topological magnetic textures Place : IRIG/SPINTEC, […]

On Monday June 26th, at 11:00, Laura Álvaro Gómez will defend her PhD thesis entitled : Current-induced motion of magnetic domain walls in cylindrical nanowires with chemical modulations Place : University of Madrid. This joint Phd defense between Université Grenoble Alpes (SPINTEC) and Universidad Complutense de Madrid (IMDEA) will be held in an hybrid mode […]

  We combined chemical synthesis, magnetic microscopy and micromagnetic simulations to provide a comprehensive view of the micromagnetics of chemical modulations in cylindrical nanowires. This sets the ground for their use to investigate the specific aspects of domain-wall dynamics and spin waves in a curvilinear system. Curvilinear and three-dimensional magnetism are a fast-developing field, considering […]

You find here the list of proposals for Master-2 internships to take place at Spintec during Spring 2023. In most cases, these internships are intended to be suitable for a longer-term PhD work. Interested Master-1 students are also encouraged to apply, as well as students not phased for a Spring internship, especially those coming from […]

Perpendicular-shape-anisotropy magnetic random-access memory (PSA MRAM) has been proposed to maintain the thermal stability of solid-state magnetic bits down to a few nanometers in diameter. Here we confirm directly with high-spatial resolution and high-sensitivity electron holography that magnetization is weakly affected by temperature, in contrast with the conventional ultrathin MRAM cells. Magnetic random-access memory (MRAM) […]
