Spin-torque-nanodiodes based on magnetic tunnel junctions are promising candidates for RF energy harvesters and ultra-low power wake-up receivers with performances that are expected to surpass those of semiconductor diodes. Experiments on magnetic tunnel junctions with perpendicular magnetic anisotropy show how the performances can be optimized upon reducing the magnetic layer thickness and the device […]

You find here the list of proposals for Master-2 internships to take place at Spintec during Spring 2023. In most cases, these internships are intended to be suitable for a longer-term PhD work. Interested Master-1 students are also encouraged to apply, as well as students not phased for a Spring internship, especially those coming from […]

Perpendicular-shape-anisotropy magnetic random-access memory (PSA MRAM) has been proposed to maintain the thermal stability of solid-state magnetic bits down to a few nanometers in diameter. Here we confirm directly with high-spatial resolution and high-sensitivity electron holography that magnetization is weakly affected by temperature, in contrast with the conventional ultrathin MRAM cells. Magnetic random-access memory (MRAM) […]

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 […]
