SPINTEC is opening a two years post-doctoral position on modelling of all optical switching using light carrying orbital momentum The manipulation of magnetization by ps or fs light pulses has become a very exciting topic nowadays opening routes towards ultrafast magnetization control. To date, most of the light-spin interaction studies made use of spin angular […]

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 […]

Van der Waals (vdW) layered magnets are promising materials to develop ultracompact and multifunctional spintronics devices. However, most of them are magnetic only at low temperature and are almost exclusively studied in the form of small flakes obtained by mechanical exfoliation. Here, we demonstrate the direct growth by molecular beam epitaxy of Fe5GeTe2, a room […]

Magnetic Random Access Memory recently started to be commercialized by all main microelectronics factories. In MRAM, the information is coded via parallel or antiparallel magnetic configurations to represent ones and zeroes. The technology is intrinsically nonvolatile, meaning it can keep information without being electrically powered. However, nonvolatility often comes with a trade-off between the information […]

Significant Dzyaloshinskii–Moriya interaction (DMI) and perpendicular magnetic anisotropy (PMA) at interfaces comprising hexagonal boron nitride (h-BN) and cobalt (Co) remaining stable over a large range of Co film thickness are reported. Furthermore, it is demonstrated that that such significant DMI and PMA give rise to the formation of skyrmions with small applied external fields. Interfacial […]

Neuromorphic computing is a bio-inspired technology which aims at mimicking the brain working principles. It can be used for fast and energy-efficient applications through the implementation of networks of artificial neurons and synapses. Artificial synapses are implemented as electronic components called memristors. These are non-volatile memory devices whose resistance can take several intermediate values between […]

This introductory course aims at helping students, researchers and engineers having little or no background in magnetism to better understand the physics and working principles of this new class of magnetic memory called MRAMs (Magnetic Random Access Memory) based on magnetic tunnel junctions. MRAM and particularly the STT-MRAM (Spin-Transfer-Torque RAM) are attracting an increasing interest […]

You find here the list of proposals for Master-2 internships to take place at Spintec during Spring 2022. 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 […]

We have conducted time-resolved stroboscopic imaging of the magnetization dynamics in cylindrical nanowires subject to nanosecond pulses of electric current. These confirm the dramatic impact of the Œrsted field in the cylindrical geometry. Through a thorough quantitative analysis, we extract features during the pulse of current, such as the azimuthal component of magnetization in magnetic […]
