This result constitutes the first step towards the fabrication ... - Misalign to write faster (October 17th, 2016)
The writing in conventional magnetic memories based on magnetic tunnel junctions (STT-MRAM) is intrinsically stochastic : a large amplitude thermal fluctuation is required to trigger the siwthing of the storage layer magnetization. SPINTEC has shown ... - Editor – Proceedings of the IEEE, Special issue on Spintronics (October 01st, 2016)
Special issue on Spintronics, published in the proceedings of the IEEE, vol.104 (10), October 2016 Editors: Hideo Ohno, Mark Stiles, Bernard Dieny - Spin super-conduction in electric insulators. (September 27th, 2016)
Magnonic is an emerging research field, which aims at exploiting the transport of pure spin current in magnetic materials. The elementary excitations are the propagating spin-waves, also called magnons, which are bosonic quasiparticles.
