We demonstrate that single pulse all optical helicity independent switching can be generalized for a large range of rare earth–transition metal multilayers. The threshold fluence for switching is observed to be independent of the pulse duration and, at high laser intensities, concentric ring domain structures are induced, unveiling multiple fluence thresholds. These striking switching features […]

We demonstrate that a perpendicular magnetic tunnel junction (MTJ) is capable of emulating an artificial spiked neuron. The magnetic stack has been designed so that the MTJ has two free layers, whose magnetization can be driven in a windmill-like dynamic by the spin transfer torque. The output-spiking rate is tunable by the dc bias voltage. […]

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 […]
