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 […]

The rapid development of information technology (IT) has had profound consequences on most aspects of our civilization. However, the energy consumption associated to IT continues to rise at an accelerated pace. In this context the microelectronics industry faces major challenges related to power dissipation and energy consumption. A promising solution is the integration of non-volatile […]

Researchers at SPINTEC Grenoble, in collaboration with PHELIQS & CIME Grenoble and LOMA Bordeaux, demonstrated how the superconducting proximity effect can be used to evaluate the penetration of Cooper pairs in metallic antiferromagnets. These findings represent a stimulating example of how antiferromagnets and superconductors may envision a common future by showing how to infer essential […]

This introductory course aims at helping students, researchers and engineers having little or no background in magnetism to better understand the physics and working principles of this new class of magnetic memory called MRAMs (Magnetic Random Access Memory) based on magnetic tunnel junctions. MRAM and particularly the STT-MRAM (Spin-Transfer-Torque RAM) are attracting an increasing interest […]
