We have fabricated large-scale two-dimensional transition metal dichalcogenide (2D TMD) MoSe2, a promising candidate for electronics, valley-spintronics and optoelectronics, on insulating sapphire and have investigated its structural and transport properties. We have shown that the ... - Creation of unidirectional spin-wave emitters by utilizing interfacial Dzyaloshinskii-Moriya interaction (April 13th, 2017)
We have created an analytical model of spin waves in microscopic spin-wave waveguides in the presence of interfacial Dzyaloshinskii-Moriya interaction. By comparing to micromagnetic simulations, we have demonstrated that spatially periodic excitation sources can be ... - Magneto-optical micromechanical systems for magnetic field mapping (February 17th, 2017)
Magnetic field mapping techniques have continuously been developed due to the necessity for determining the spatial components of local magnetic fields in many industrial applications and fundamental research. Several factors are considered for sensors such ... - Evidence for spin-to-charge conversion by Rashba coupling in metallic states at the Fe/Ge(111) interface (January 09th, 2017)
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 ... - 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. 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 ... - Des skyrmions magnétiques observés à température ambiante (February 09th, 2016)
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 ... - Perpendicular magnetic tunnel junctions with double barrier and single or synthetic antiferromagnetic storage layer (September 02nd, 2015)
Perpendicular magnetic tunnel junctions with double barrier and single or synthetic antiferromagnetic storage layer, Cuchet, L., Rodmacq, B., Auffret, S., Sousa, R.C., Prejbeanu, I.L., Dieny, B., Journal of Applied Physics, 117 (23), 233901 (2015) - Correlation Between Disordered Magnetic Phases in Ferromagnetic/Antiferromagnetic Thin Films and Device-to-Device Variability of Exchange Bias in Spintronic Applications (August 31st, 2015)
Correlation Between Disordered Magnetic Phases in Ferromagnetic/Antiferromagnetic Thin Films and Device-to-Device Variability of Exchange Bias in Spintronic Applications Spintronic applications rely on ferromagnetic/antiferromagnetic exchange biased bilayers. In this study, we show whether and how disordered magnetic ...
