  Control over spin transport in antiferromagnetic systems is essential for future spintronic applications with operational speeds extending to ultrafast time scales. A consortium of physicists at SPINTEC, JGU Berlin and Charles University Prague established the essential role of interfaces for spin current injection and spin current-to-charge current conversion, from the gigahertz (GHz) diffusive to […]

Magnetic skyrmions are appealing for use in logic and memory devices combining small size and fast motion. Here, we propose to exploit skyrmion interactions to perform both logic and memory operations at the nanoscale. Our concept opens a path for novel devices which intrinsically merge high-density non-volatile data storage with computing capabilities. a. Schematic representation […]

R&D Engineer position proposal

Title: Design for memory/logic devices Keywords: Design, post-CMOS electronics, spintronics, architectures, ferroelectrics, magneto-electric spin-orbit Summary:Spintronics devices involve ferromagnetic elements with high switching energies. Contrastingly, the polarization of ferroelectrics can be easily switched by an electric field, at energies typically 1000 times lower. As recently demonstrated by Intel, this makes ferroelectrics good candidates for ultralow-power post-CMOS […]

Contrastingly, the polarization of ferroelectrics can be easily switched by an electric field, at energies typically 1000 times lower. This makes ferroelectrics good candidates for ultralow-power neuromorphic AI architectures. We recently demonstrated in a Nature article […]

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) […]

Context. Spintronics has become a mature technology for applications, such as magnetic field sensing and solid-state memories. However, existing concepts are almost exclusively based on planar processes such as thin film deposition and patterning. Extending spintronics to 3D devices would provide new integrated functionalities such as three-dimensional magnetic field sensors, and also open prospects for […]
