SPIN ORBITRONICS

Overview

From new concepts to devices : we are exploring new concepts in spintronics based on spin dependent transport with various systems; structure inversion asymmetry (spin orbit torques, Rashba effect, Spin Hall Effect, Topological Insulators), and alternative geometries in order to develop innovative architectures of devices.

Research directions

Spin Orbit Torques

particles

We aim at understanding and mastering spin orbit torques for efficient and deterministic magnetization switching with in plane currents.

Spin to charge inter-conversion

particles

We study different mechanisms to inter-convert spin and charge currents using spin orbit interaction: Spin Hall effect, Rashba effect at interfaces and surfaces of Topological insulators.

3-Terminal MRAM

particles

We develop electrically addressable non-volatile memories combining high speed and infinite endurance.

Novel devices and concepts

particles

We study spin dependent transport and pure spin current physics in lateral spin valves as well as novel ways to tailor the magnetic states of nanomagnets, like magnetic origamis.
