Nanostructured ZnFe2O4: An Exotic Energy Material

Autor: Murtaza Bohra, Vidya Alman, Rémi Arras

Publikováno v: Nanomaterials, Vol 11, Iss 5, p 1286 (2021)

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

Publikováno v: Physical Review B. 103

We report a study based on first-principles calculations complemented by a tight-binding approach and a k⋅p model of the spin-orbit effects in epitaxially strained PbTiO3. The imposed biaxial tensile strain allows us to rotate the electrical polari

Purely cubic spin splittings in the band structure of bulk insulators have not been extensively investigated yet despite the fact that they may pave the way for novel spin-orbitronic applications and can also result in a variety of promising spin phe
