For the future integration of 2D materials in spintronic devices (sensors, memories…), the ability to grow van der Waals (vdW) heterostructures combining 2D magnets, high mobility, high spin-orbit coupling (SOC) or topological materials on large areas constitutes a real challenge today. Here, by using molecular beam epitaxy in the van der Waals regime, we could […]

Spin-orbit torques (SOTs) have the potential to manipulate magnetization using in-plane current, and two-dimensional electron gases (2DEGs) provide a highly efficient spin-to-charge current interconversion. This paper reports the non-volatile electric-field control of SOTs in an oxide-based Rashba-Edelstein 2DEG.   We recently reported a significant progress in the path towards a next generation of memory devices […]

Albert Fert, Mairbek Chshiev, André Thiaville and Hongxin Yang, J. Phys. Soc. Jpn. 92, 081001 (2023).   In this Review article, the authors briefly introduce the research history of DMI and its significance in the field of modern spintronics. Since the early 1960’s, the discovery of Dzyaloshinskii–Moriya interaction (DMI) helped to explain the physical mechanisms […]

A new type of magnetic sensor based on the spin transfer torque using 50-100nm diameter perpendicular magnetic tunnel junctions was recently reported in the IEEE Sensors Journal. The paper demonstrates the magnetic field sensing principle, patented by Spintec in 2020, while also describing possible read-out methods and their associated signal conditioning electronics. Improvements over conventional […]

Pedro BRANDAO VEIGA is among Best Poster Award winners at INTERMAG 2023 Conference taking place in May 2023 in Sendai, Japan. The title of his poster is “Engineering of Voltage-Controlled Magnetic Tunnel Junctions at Cryogenic Temperatures” with results predicting the existence of a deterministic switching regime that, coupled with lower switching energies, will be advantageous […]

Théo FROTTIER is among Best Poster Award winners at INTERMAG 2023 Conference taking place in May 2023 in Sendai, Japan. The title of the poster prepared with Aurélie KANDAZOGLOU, Cécile GREZES of Topological Spintronics team is “Non-Volatile Electric-Field Control of Spin-Orbit Torques and Anomalous Hall Effect in Perpendicular Ferromagnet-SrTiO3 systems”. The presented results clearly show […]

The Dzyaloshinskii–Moriya interaction (DMI) arising in the magnetic systems with broken inversion symmetry plays an essential role in topological spintronics. Using atomistic spin model simulations of an intriguing type of DMI emerging in the films with composition gradient (g-DMI), it is demonstrated that that both the strength and chirality of g-DMI can be controlled by […]
