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 […]

SPINTEC has currently several postdoc positions open to work on spintransfer-torque nano-oscillators based on magnetic tunnel junctions. Spintorque driven excitations within magnetic tunnel junctions show a large range of interesting, non-linear dynamic effects that are promising for low power implementations within wireless communication or unconventional computing systems. The different projects address at the same time […]

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 […]

Libor VOJACEK is the Best student award winner as well as among Best poster award winners at IEEE Magnetics Society Summer School 2023 that took place in Bari, Italy. The title of his poster is “Spin transport in CrXY Janus monolayers: multiscale computational study” with results predicting the existence of a deterministic switching regime that, […]

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 […]

On Thursday, March 16 2023, we have the pleasure to welcome in SPINTEC Julien Tranchida, Research Scientist at CEA Cadarache. He will give us a seminar at 14:00, entitled: Coupled magnetic and molecular dynamics: Methodology and application to the simulation of magneto-elastic effects in iron Place: SPINTEC Seminar, CEA Building 10.05 auditorium 445 (access needs […]

  We combined chemical synthesis, magnetic microscopy and micromagnetic simulations to provide a comprehensive view of the micromagnetics of chemical modulations in cylindrical nanowires. This sets the ground for their use to investigate the specific aspects of domain-wall dynamics and spin waves in a curvilinear system. Curvilinear and three-dimensional magnetism are a fast-developing field, considering […]

  Spin-torque-nanodiodes based on magnetic tunnel junctions are promising candidates for RF energy harvesters and ultra-low power wake-up receivers with performances that are expected to surpass those of semiconductor diodes. Experiments on magnetic tunnel junctions with perpendicular magnetic anisotropy show how the performances can be optimized upon reducing the magnetic layer thickness and the device […]

Magnetic skyrmions are appealing for use in logic and memory devices combining small size and fast motion. Here, we propose to exploit skyrmion interactions to perform both logic and memory operations at the nanoscale. Our concept opens a path for novel devices which intrinsically merge high-density non-volatile data storage with computing capabilities. a. Schematic representation […]

Magnetic skyrmions are localized chiral spin textures, which offer great promise to store and process information at the nanoscale. The unique sense of rotation of their surrounding domain wall, called chirality, is resulting from the so-called Dzyaloshinskii−Moriya Interaction. C.E. Fillion et al. have managed the inversion of the skyrmion chirality by applying a gate voltage, […]
