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, […]

Skyrmions in synthetic antiferromagnets are appealing for use in future memory and computing devices, combining small size and fast motion, but creating, stabilizing, and observing them remains a challenge. Here, we demonstrate the stabilization and current and light induced nucleation of skyrmions in a synthetic antiferromagnet, observing the magnetization texture in each layer using X-ray […]

A new form of spintronic is emerging, exploiting electrical insulators. Recent spectroscopic studies performed at SPINTEC have revealed the coherent coupling that may establish between two distant macrospins separated by a non-magnetic dielectric spacer via circularly-polarized acoustic phonons that carry angular momentum information. This long-range effect represents an important progress in magnonics and spin wave […]

A recent breakthrough in understanding the thermal effects on the magnetic properties of perpendicularly magnetized Fe/MgO interfaces is reported. It turns out that the macroscopic mechanisms play a decisive role in determining the thermal stability of magnetization in such structures. The perpendicular magnetic anisotropy (PMA) at magnetic transition metal/oxide interfaces(TM/Ox) is a key element in […]

SPINTEC involved in the PEPR electronics recently funded by the French government in the framework of the national France 2030 strategy On July 12, 2022, the President of the Republic presented in Crolles the France 2030 national investment strategy for the electronics sector. France 2030 will dedicate more than 5 billion euros to support the […]

France is investing more than 38M€ in Spintronics thanks to the PEPR-SPIN exploratory program! SPIN is among the 13 new exploratory programs winners of the second wave of calls for projects Priority Programs and Equipment for Exploratory Research (PEPR). Funded by France 2030, this action (€1 billion) aims to launch research programs in emerging scientific […]
