— The general purpose of spin-electronics is to take advantage of the spin of the electrons in addition to their electrical charge to conceive innovative electronic components. These components combine magnetic materials which are used as spin-polarizer or analyzer together with semiconductors or insulators. SPINTEC Laboratory works on the development of(More)
The possibility of exciting microwave oscillations in a nanomagnet by a spin-polarized current, as predicted by Slonczewski and Berger, has recently been demonstrated. This observation opens important prospects of applications in radiofrequency components. However, some unresolved inconsistencies are found when interpreting the magnetization dynamics within(More)
We present, herein, an extended study of the half-Heusler alloy NiMnSb, starting with the deposition technique, continuing with the basic structural and magnetic properties of the thin films, and finishing with the electronic and compositional properties of their surfaces. The experimental methods we apply combine magnetization and magnetoresistivity(More)
Spintronics (or spin-electronics) is a continuously expending area of research and development at the merge between magnetism and electronics. It aims at taking advantage of the quantum characteristic of the electrons, i. e. its spin, to create new functionalities and new devices. Spintronic devices comprise magnetic layers which serve as spin polarizers or(More)
— The recent advent of spin transfer torque (STT) has shed a new light on MRAM with the promises of much improved performances and greater scalability to very advanced technology nodes. As a result, MRAM is now viewed as a credible solution for stand-alone and embedded applications where the combination of non-volatility, speed and endurance is key. Whereas(More)
