On December 20th at 11:00, we have the pleasure to welcome Dr. Yaroslav Kvashnin from Uppsala University who will give a seminar at CEA/SPINTEC, Bat 1005, room 445, entitled : Magnetic interactions and excitations from first principles Magnetization dynamics on the nanoscale can be well described by Landau-Lifshitz(-Gilbert) equation of motion. If properly parameterized, it […]

Domain-wall motion in one-dimensional conduits is both a textbook case for magnetization dynamics and the understanding of spin torques, and of practical importance for the design of novel spintronic ICT devices. However, instabilities known as Walker breakdown limit the speed in most cases. We have shown experimentally and confirmed by simulation, that these instabilities are […]

We propose an original concept of spintronic memristor based on the angular variation of the tunnel magnetoresistance (TMR) of a nanopillar comprising several magnetic layers. We have experimentally developed the appropriate magnetic free layer and integrated it in a full nanosized magnetic tunnel junction pillar. In parallel, we developed a model describing the magnetization dynamics […]

You find here the list of proposals for Master-2 internships to take place at Spintec during Spring 2020. 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. You may download the full list of proposals, along with an introduction to the […]

Domain wall propagation in modulated-diameter cylindrical nanowires is a key phenomenon to be studied with a view to designing three-dimensional magnetic memory devices. In this framework, we quantified theoretically the driving force needed for a domain wall to overcome the potential barrier related to modulated diameter geometry in order to jump from one stable position […]

A complete set of the generalized drift-diffusion equations for a coupled charge and spin dynamics in ferromagnets in the presence of extrinsic spin-orbit coupling is derived from the quantum kinetic approach, covering major transport phenomena, such as the spin and anomalous Hall effects, spin swapping, spin precession, and relaxation processes. It is argued that the […]

Despite being a weak spin–orbit coupling material, graphene demonstrated to induce significant Dzyaloshinskii–Moriya interaction due to the Rashba effect leading to formation of chiral spin textures in adjacent ferromagnet (FM) at graphene/FM interfaces. First-principles calculations and experiments using spin-polarized electron microscopy show that this graphene-induced Dzyaloshinskii–Moriya interaction can have a similar magnitude to that at […]

On november 28, We have the pleasure to welcome Bertrand Dupé from INSPIRE Group, Institute of Physics, Johannes Gutenberg University Mainz, Germany. He will give us a seminar at 11:00, CEA/Spintec, Bat. 1005, room 434A entitled : Topological spintronics Surfaces and interfaces can host a wide range of physical phenomena: changes of chemical potential or […]

Due to the nanometer size of magnetic tunnel junctions and high interfacial resistance of ultrathin MgO tunnel barriers, temperature modulation at GHz frequency can be achieved in these devices and efficiently use to amplify microwaves in spintronics oscillators. Spintronics oscillators use two major phenomena discovered in spin-electronics: the tunnel magnetoresistance of magnetic tunnel junctions (MTJ) […]
