A full hybrid magnetic/CMOS System on Chip (SoC), embedding analog and digital functions based on spintronics devices on the same die, has been designed and sent to manufacturing. It is the first demonstrator of such ... - Single-particle mass spectrometry with nanomechanical resonators (October 04th, 2018)
Mass spectrometry (MS) is an essential tool in a broad variety of fields, with good efficiency up to the kDa mass range (~10-21 g). We demonstrate here Nano-electro-mechanical systems mass spectroscopy (NEMS-MS) with arrays of ... - Highly Efficient Spin-to-Charge Current Conversion in Strained HgTe Surface States Protected by a HgCdTe Layer (October 03rd, 2018)
We report the observation of spin-to-charge current conversion in strained mercury telluride at room temperature, using spin pumping experiments. We show that a HgCdTe barrier can be used to protect the HgTe from direct contact ... - High speed and low area look-up table design based on MRAM memory (September 07th, 2018)
Continual growth in the size and functionality of FPGA over few years leads to an increasing interest in their use for high speed applications. However, the memory access speed limits the execution speed. The great ... - Sub-10nm thermally stable Perpendicular Shape Anisotropy magnetic memory (August 24th, 2018)
A new concept of thermally stable and electrically switchable Spin Transfer Torque Magnetic Random Access Memory (STT-MRAM) scalable to diameter down to 4nm was proposed and demonstrated. By dramatically increasing the thickness of the storage ... - Nonlinear properties of pure spin conductors (June 21st, 2018)
