Integrated Circuits (ICs) have to be protected against threatening environmental radiations and malicious perturbations. A large panel of countermeasures have been developed to answer the needs of this challenging field. This work proposes an innovative sensor to detect both photoelectrical injections and thermal perturbations aiming a circuit. This architecture is designated by “Dual Detection of […]

Relating magnetotransport properties to specific spin textures at surfaces or interfaces is an intense field of research nowadays. Here, we investigate the variation of the electrical resistance of Ge(111) under the application of an external magnetic field. We find a magnetoresistance term that is linear in current density j and magnetic field B, reaching 0.5 […]

The Hall effect can be extended by inducing a temperature gradient in lieu of electric field that is known as the Nernst effect. After the discovery of the spin Nernst effect, the collection would not be complete without mentioning the valley degree of freedom benchmarked by the observation of the valley Hall effect in transition […]

A possibility of controlling electronic and magnetic properties of graphene via proximity of multiferroic substrate is demonstrated. Coupling graphene to a multiferroic oxide (bismuth ferrite) give rise to novel class of spin-dependent transport phenomena based on multiferroic-induced proximity effects in graphene. Based on these findings, a concept of multi-resistive device in lateral geometry is proposed. […]

The generation of a spin current and its further conversion to a charge current have attracted considerable attention, facilitating advances in basic physics along with the emergence of closely related applications in the field of spintronics. In this study, we experimentally and theoretically demonstrated the self-induced inverse spin Hall effect for spin-charge conversion, triggered by […]

We found that Mn4N, a rare-earth free ferrimagnet made of abundant elements, is an exciting candidate for the development of sustainable spintronics devices. This material possess exciting properties, and in particular domain walls can be moved at record speeds by spin-polarized currents, in absence of any external magnetic field. This is explained by the large […]

Domain-wall motion in one-dimensional conduits is both a textbook case for magnetization dynamics and the understanding of spin torques, and of practical importance for the design of novel spintronic ICT devices. However, instabilities known as Walker breakdown limit the speed in most cases. We have shown experimentally and confirmed by simulation, that these instabilities are […]

We propose an original concept of spintronic memristor based on the angular variation of the tunnel magnetoresistance (TMR) of a nanopillar comprising several magnetic layers. We have experimentally developed the appropriate magnetic free layer and integrated it in a full nanosized magnetic tunnel junction pillar. In parallel, we developed a model describing the magnetization dynamics […]

Phys. 91, 035004 (2019) Spin-orbit coupling in inversion-asymmetric magnetic crystals and structures has emerged as a powerful tool to generate complex magnetic textures, interconvert charge and spin under applied current, and control magnetization dynamics. Current-induced spin-orbit […]

Spin Orbit Torque Magnetic RAM (SOT-MRAM) approach represents a new way to overcome Spin Transfer Torque (STT) memory limitations by separating the reading and the writing paths. It is particularly interesting for high-speed applications that do not require very high density because of two transistors per bit cell. This work introduces a high-density SOT-MRAM memory […]
