STOCHNET stands for Hybrid Stochastic Tunnel Junction Circuits for Optimization and Inference. The motivation behind StochNet is to explore — through experimental demonstrations with hybrid CMOS stochastic tunnel junction circuits and simulations of theoretical architectures — the technological feasibility of recently explored brain inspired computing frameworks that point towards neural stochasticity as being fundamental to […]

In the frame of the joint US-French NSF-ANR project StochNet, Spintec laboratory is opening a postdoctoral researcher position. The candidate will work on stochastic magnetic tunnel junctions grown and fabricated at Spintec, and will use them to explore brain-inspired schemes promising for building energy-efficient computing hardware. The project will have a strong interdisciplinary aspect (Spintronic, […]

The broken inversion symmetry of some semiconductors may allow for spin–charge interconversion, but its control by electric fields is volatile. This has led to interest in ferroelectric Rashba semiconductors, which combine semiconductivity, large spin–orbit coupling and non-volatility. Here we report room-temperature, non-volatile ferroelectric control of spin-to-charge conversion in epitaxial germanium telluride films. Spintronics could potentially […]

Significant Dzyaloshinskii–Moriya interaction (DMI) and perpendicular magnetic anisotropy (PMA) at interfaces comprising hexagonal boron nitride (h-BN) and cobalt (Co) remaining stable over a large range of Co film thickness are reported. Furthermore, it is demonstrated that that such significant DMI and PMA give rise to the formation of skyrmions with small applied external fields. Interfacial […]

Neuromorphic computing is a bio-inspired technology which aims at mimicking the brain working principles. It can be used for fast and energy-efficient applications through the implementation of networks of artificial neurons and synapses. Artificial synapses are implemented as electronic components called memristors. These are non-volatile memory devices whose resistance can take several intermediate values between […]

Using the spin Seebeck effect (SSE), we study the short-range propagation distance of thermally-induced spin currents inside insulator magnetic thin film. We find the spin diffusion length of thermal magnons (magnons carrying quanta of energy, kBT) is is in submicron range.   The vision of spintronics is to use the spin of an electron rather […]
