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 […]

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 […]

Spintec is part of a European-funded ITN project called SPEAR: Spin-orbit materials, emergent phenomena and related technology training. The project, coordinated by CIC nanoGUNE, seeks to explore new materials for the next generation of computer memories and processors. six European academic institutions (CEA-France, ETH Zürich-Switzerland, IMEC-Belgium, U. Hamburg-Germany, Martin Luther University Halle–Germany, CIC Nanogune) and […]

You find here the list of proposals for Master-2 internships to take place at Spintec during Spring 2021. 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. You may download the […]

Grenoble Alpes will defend his HDR (Ability to Supervise Research) entitled : Nanostructures of disordered 3D topological insulators Place : CEA Building 10.05 auditorium 445  (contact : romain.giraud@cea.fr) Visio : Participants using a workstation can join with this link Skype Meeting, or directly via the […]

Layered magnetic topological insulators are candidate to unveil novel electronic phases controlled by the magnetization. In MnBi4Te7, we evidenced a transition from an antiferromagnetic to a ferromagnetic-like metamagnetic state, possibly realizing the quantum anomalous Hall regime in ultra-thin films above 1K. 3D topological insulators ideally have an insulating bulk and 2D gapless topological surface states […]

Paul Noël has been awarded one out of the 9 awards of the University Grenoble Alpes, for PhDs defended in 2019. Paul Noël conducted his PhD work at SPINTEC, under the co-supervision of Jean-Philippe Attané and Laurent Vila, in the Spinorbitronics team. Part of the work has been conducted in collaboration with UMPhy CNRS/Thales. The […]

Electron spin—a fundamentally quantum property—is central to spintronics, a technology that revolutionized data storage, and that could play a major role in creating new computer processors. In order to generate and detect spin currents, spintronics traditionally uses ferromagnetic materials whose magnetization switching consume high amounts of energy. In the April 22, 2020 issue of Nature, […]

We found that Mn4N, a rare-earth free ferrimagnet made of abundant elements, is an exciting candidate for the development of sustainable spintronics devices. This material possess exciting properties, and in particular domain walls can be moved at record speeds by spin-polarized currents, in absence of any external magnetic field. This is explained by the large […]
