The cryogenic system that cools the superconducting magnets on the Japanese Tokamak JT-60SA reactor has a refrigeration capacity of about 9 kW equivalent at 4.5 K, and the reactor’s cyclical operation creates substantial variations in the heat loads the system must handle. From 2010 to 2016, when the CEA was designing the cryogenics for the […] >>

The tiny magnetic bubbles known as skyrmions—potential candidates for tomorrow’s memory bits—can now be stabilized at ambient temperature without a magnetic field. Researchers at Spintec just demonstrated this new capability using an exchange coupler already used in MRAM. Specifically, an anti-ferromagnetic layer is combined with the ultra-thin ferromagnetic layer that holds the skyrmions.The size of […] >>

Clinatec has been trying to effectively determine the best location in the brain for its WIMAGINE® implant, which measures the brain activity of tetraplegic patients. The data is used to control an exoskeleton, restoring these patients’ mobility and independence. Where to implant the device is a key challenge for Clinatec. Researchers at the center have […] >>

Lattice constant is a measure of how structurally compatible two materials are. Researchers from Irig and Institut Néel recently reduced these differences for GaAs/InAs (gallium arsenide/indium arsenide) nanowires. Their approach was to form a 5 nm ternary (InGaAs) alloy interface between the materials. The alloy’s composition transitions from a composition close to GaAs to one […] >>

How do you reconstruct the C-face of a silicon carbide (SiC) wafer after cutting? The issue has been the subject of great debate since an early observation that dates back to 1997. An international team led by Irig simulated a novel approach to surface reconstruction never before used for semiconductors. The research was published in […] >>
