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 […]

We report a theoretical overview of the magnetic domain wall behavior under an electric current in infinitely long nanotubes with azimuthal magnetization. We highlight effects that, besides spin-transfer torques already largely understood in flat strips, arise specifically in the tubular geometry: the Œrsted field and curvature-induced magnetic anisotropy resulting both from the exchange interaction and […]

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 […]

Arne Brataasa, Bart van Wees, Olivier Klein, Grégoire de Loubens, Michel Viret, Physics Reports 885, 1-27 (2020) Spin insulatronics covers efforts to generate, detect, control, and utilize high-fidelity pure spin currents and excitations inside magnetic insulators. Here, the authors review recent developments to realize electric and thermal generation, manipulation, detection, and control of pure spin […]

Voltage-driven ionic transport in magnetic materials has traditionally relied on controlled migration of oxygen ions. In this work, led by researchers at UAB (Barcelona) in collaboration with colleagues at Georgetown Univ. (D.C.), IMN-CNM-CSIC (Madrid), Spintec (Grenoble), HZDR (Dresden), ICN2 and IMB-CNM-CSIC (Barcelona), room-temperature voltage-driven nitrogen transport is demonstrated using electrolyte-gating of a CoN film. The […]

SPINTEC is opening a Professorship position, with competition to take place during Spring 2021. The research scope is theory and numerical simulation, covering all aspects from fundamental to applied spintronics in the broadest sense. The research focus is the modeling of specific properties induced by spin-orbit effects, with the aim on the one hand to […]
