Millimeter-scale layered MoSe2 grown on sapphire and evidence for negative magnetoresistance (April 14th, 2017)
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 layered MoSe2 exhibits characteristics of a stoichiometric 2H-phase, a van der Waals epitaxy regarding the substrate and we have evidenced […]

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 used to create a uni-directional spin-wave-emission source whose properties can be predicted by our model. Since miniaturization of CMOS devices […]
Read moreMagneto-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 as spatial resolution, sensitivity, linear response, required proximity to the sample, as well as the ability to filter noise and […]
Read moreEvidence 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 of a spin transistor based on the spin-orbit coupling. The spin-orbit coupling, relating the electron spin and momentum, has long […]
Read moreMisalign 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 that this stochasticity can be almost completely suppressed by inducing an oblique anisotropy (easy-cone anisotropy) in the storage layer. This […]

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 electronic devices are a significant reduction in energy consumption thanks to the absence of Joule heating, as well as new features taking […]
Read moreComparison 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 found to be one order of magnitude larger. In addition to using the electric charge of the electron, spintronic technologies […]
Read moreA 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 saying that the air-flow generated by rotating the blades of a fan can propagate in a neighboring room if the […]
