    We have demonstrated the spin-to-charge interconversion by Rashba coupling at the interface between two light materials: iron and germanium which is compatible with today’s CMOS technology. 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 ...
  • 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. The advantages over conventional ...
  • Comparison of the use of NiFe and CoFe as electrodes for metallic lateral spin valves (May 17th, 2016)
    A CoFe based ferromagnetic alloy has been used in lateral spin valves to replace NiFe alloys, which are overwhelmingly exploited as ferromagnets electrodes in lateral spintronic devices. By using this second material, emitted signals are ...
  • A fluctuating magnetic order allows more spins to pass through an interface (February 26th, 2016)
    Bringing a ferromagnetic layer to resonance creates non-equilibrium magnetization dynamics which generates a spin current. The spin current propagates from the ferromagnet into a neighboring layer if permitted by the interface. This is equivalent to ...

    Ces structures magnétiques nanométriques ont été observées à températures ambiante dans des matériaux compatibles avec l’industrie électronique. Ces résultats font sauter un verrou important quant à l’utilisation des skyrmions comme vecteur d’information ...
  • Magnetic Origami (January 08th, 2016)
    Magnetic Origami Magnetic devices made from the same thin film and subjected to the same electric excitation switch opposite to each other due to their different shape. Mihai MIRON The magic about the art of paper folding is ...
  • Giant enhancement of magnetic effect will benefit spintronics (January 08th, 2016)
    Giant enhancement of magnetic effect will benefit spintronics Researchers from Spintec have demonstrated that coating a cobalt film in graphene doubles the film’s perpendicular magnetic anisotropy (PMA), so that it reaches a value 20 times higher ...
