More people, more cities; the energy demand increases in consequence and much of that will rely on next-generation smart materials. Zn-ferrites (ZnFe2O4) are nonconventional ceramic materials on account of their unique properties, such as chemical an

Robustness of the Half-Metallicity at the Interfaces in Co2MnSi -Based All-Full-Heusler-Alloy Spintronic Devices

Autor: L. Calmels, Rémi Arras, Barthélémy Pradines

Publikováno v: Physical Review Applied. 15

Based on first-principles methods, we demonstrate that it would be possible to design efficient all-full-Heusler-alloy-based spintronic devices associating ${\mathrm{Co}}_{2}\mathrm{Mn}\mathrm{Si}$ electrodes and nonmagnetic full-Heusler-alloy spacer

Schottky barrier formation at the Fe/SrTiO3 (001) interface: Influence of oxygen vacancies and layer oxidation

Autor: Philippe Schieffer, Rémi Arras, J. Gosteau, Sylvain Tricot

Publikováno v: Physical Review B. 102

Schottky barrier formation at metal/insulating oxide interfaces relies on complex mechanisms which are difficult to unravel. We propose a detailed numerical study of the atomic, magnetic, and electronic properties of the $\mathrm{Fe}/\mathrm{Sr}\math

First-principles simulations are conducted to predict that ferroelectric nitride perovskite $\mathrm{LaW}{\mathrm{N}}_{3}$ not only exhibits large spin splittings (2.7 eV \AA{}) but also possesses unique spin textures for some of its conduction level
