Engineering the magnetic coupling and anisotropy at the molecule–magnetic surface interface in molecular spintronic devices

Publikováno v: Nature Communications, Vol 7, Iss 1, Pp 1-10 (2016)

Controlling the magnetic response of a molecular device is important for spintronic applications. Here the authors report the self-assembly, magnetic coupling, and anisotropy of two transition metal complexes bound to a ferrimagnetic surface, and pro

A Wigner molecule at extremely low densities: a numerically exact study

Autor: Miguel Escobar Azor, Léa Brooke, Stefano Evangelisti, Thierry Leininger, Pierre-François Loos, Nicolas Suaud, J. A. Berger

Publikováno v: SciPost Physics Core, Vol 1, Iss 1, p 001 (2019)

In this work we investigate Wigner localization at very low densities by means of the exact diagonalization of the Hamiltonian. This yields numerically exact results. In particular, we study a quasi-one-dimensional system of two electrons that are

Impact of the electric field on isotropic and anisotropic spin Hamiltonian parameters

Publikováno v: Journal of Chemical Physics
Journal of Chemical Physics, 2022, 157 (20), pp.204308. ⟨10.1063/5.0116709⟩

One may obviously think that the best way to control magnetic properties relies on using a magnetic field. However, it is not convenient to focus a magnetic field on a small object, whereas it is much easier to do so with an electric field. Magnetoel
