Toussaint Place: ONLINE Link to participate on-line: https://grenoble-inp.zoom.us/j/93099958160 Code: 075714 Abstract: This thesis studies theoretically the magnetic domain wall behavior in cylindrical wires subjected […]

The spin absorption process in a ferromagnetic material depends on the spin orientation relatively to the magnetization. Using a ferromagnet to absorb the pure spin current created within a lateral spin valve, we evidence and quantify a sizable orientation dependence of the spin absorption in Co, CoFe, and NiFe. These experiments allow us to determine […]

Large spin Hall angles have been observed in 3d ferromagnetic materials, but their origin, and especially their link with the ferromagnetic order, remain unclear. Here, we investigated the evolution of the inverse spin Hall Effect of NiCu alloys across their Curie temperatures using spin-pumping experiments. We show that the inverse Spin Hall Effect in these […]

MARIN stands for Magnon Reservoir computINg. It is a 42 months researcher project funded by the French ANR. MARIN aims at showing that spin waves can be used in the field of “wave-computing” where oscillatory signals are proposed to perform analog non-Boolean operations such as reservoir computing (see Figure). The MARIN project will investigate experimentally […]

UFO stands for UltraFast Opto-magneto-spintronics for Futur Nanotechnologies. UltraFast Opto-magneto-spintronics is an emerging field of research that combines the ideas and concepts of magneto-optics and opto-magnetism with spin transport phenomena, supplemented with the possibilities offered by photonics for ultrafast low-dissipative manipulation and transport of information. Both light and spin currents can control magnetic order, though […]

The goal of project CRYMCO is to optimize MRAM cell concepts for operation in cryogenic temperature environments. The project will explore applications for storage in conventional and quantum information processing. In the first case, MRAM with low energy dissipation for cryogenic environments could result in power savings by operating at low temperature, when the cost/power […]

In the frame of the French national ANR project ELMAX, Spintec laboratory is opening a postdoctoral researcher position. The candidate will work on the magnetism of FeGeTe 2D ferromagnets grown by molecular beam epitaxy. The objective will be to tune the magnetic properties of 2D ferromagnets by interfacing with high spin-orbit materials (transition metal dichalcogenides […]

ELMAX stands for ELectrical Control of Magnetization in fully epitaXial van der Waals heterostructures. It is a 36 months young researcher project funded by the French ANR. The recent discovery of 2D magnets has enabled the investigation of spin devices fully made of van der Waals materials. Thanks to their two-dimensional nature, 2D magnets generally […]

SpinSpike stands for Spintronic Spiking Neurons. It is a 42-month-long ANR project (2021/2024). Spintronics has recently shown its promise for neuromorphic computing, but is lacking an essential ingredient of biological neural networks: spiking neurons. In this context, the objective of SpinSpike project is to explore novel approaches of spiking neurons using magnetic tunnel junctions. Building […]

CONTRABASS stands for Ferroelectric control of Rashba states, a 42 months ANR project starting in December 2020. 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. Combined with high spin-orbit coupling elements, ferroelectrics have also a […]
