Mn-Ni lithium batteries lose around 40% of the high capacities for which they are known on the first charge-discharge cycle. Scientists have been trying to find out why for years. A team of researchers from INAC and Leti, in conjunction with a researcher from Russia, have made two major contributions to elucidating the mystery. They […] >>

The power sensors that professional cyclists use cost more than $1,000 per unit. Leti presented a demonstrator system at CES 2017 that costs less than $100! The power sensor does not require any calibration, making it easy to use. Plus, it is compatible with all types of bicycles and is accurate to within around 8%, […] >>

Leti and LTM have developed a new class of thin-layer composites for microelectronics. The composites are made by dispersing a very high load—more than 50% of the total volume—of nanoparticles in a polymer matrix. The resulting composite delivers unrivalled properties: virtually loss-free magnetic materials up to 20 GHz, a frequency 20 times higher than the […] >>

When you stack several monolayers of cobalt to obtain perpendicular anisotropy the effect is diminished as the number of layers increases. However, when a layer of graphene is added to the stack the perpendicular anisotropy increases up to two times for twelve to thirteen monolayers.* INAC completed the calculations, which were confirmed by lab experiments […] >>

Researchers at Spintec have achieved higher STT-MRAM write speeds with lower electrical write voltage. They did it by introducing easy cone anisotropy into the storage layer; this causes a 10° to 15° misalignment between the initial magnetism of the storage layer (switchable) and the reference layer. This initial angle makes reversing magnetism faster and easier […] >>
