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 […]

The research highlights of SPINTEC over the year 2020 have been put together, and are available to download: http://www.spintec.fr/spintec-annual-booklets. This booklet contains the key facts of the lab over the period (contracts, new staff etc.), the most up-to-date description of the lab activity and the research teams. We wish you a nice reading!

Non-volatility is the main physical feature that fast memories, such as SRAM, are still lacking. Such memories could increase computing performance while reducing significantly the power consumption. The only viable option for sub-ns nonvolatile memory is the Spin-Orbit Torque Magnetic Random Access Memory (SOT-MRAM). The main roadblock towards the integration of the SOT-MRAM is that […]

Magnetic spintronic memory called STT-MRAM have recently entered in volume production at major microelectronic foundries. The research in this area is now focused on preparing the future memory generations with higher capacity, higher speed, lower power consumption, wider range of operating temperature. To conduct this type of research, it is important to be able to […]

Spintec invites application for postdoctoral positions in spintronics on electrical control of magnetic skyrmions. Magnetic skyrmions are nontrivial spiral spin textures considered as potential building blocks for ultrafast and power efficient spintronic memory and logic devices. Controlling their chirality would provide an additional degree of freedom and enable new functionalities in these devices. Achieving such […]

Antaios announced on September 16, 2020 that is has secured 11 million dollars in funding to accelerate innovation and develop new strategic partnerships. Antaios is a start-up founded in 2017 on the basis of a decade of pioneering work carried out at Spintec on SOT-MRAM. Antaios is fully engaged in bringing the SOT-MRAM technology to […]

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 […]

We demonstrate in this study a fabrication process that enables the realization of a top transparent conductive electrode of magnetic tunnel junctions (MTJs), building blocks of magnetic random access memories (MRAMs). This work opens up the realization of future and faster nonvolatile memories based on hybrid spintronic photonic circuits. This new process has been electrically […]

Magnetic skyrmions are topologically protected spin textures of great interest for nanoscale information storage and processing. However, stabilizing small skyrmions without applying an external magnetic field remains challenging. This study employs a thin ferromagnetic layer exchange-biased by an antiferromagnetic film to stabilize ferromagnetic skyrmions down to 30 nm in diameter, at zero magnetic field. In […]
