Strain manipulation of the local spin flip on Ni@B80 endohedral fullerene

Autor: Chun Li, Jing Liu, Yiming Zhang, Wolfgang Hübner, Rui Huang, Georgios Lefkidis, Wei Jin, Shuai Xu

Publikováno v: Physical Chemistry Chemical Physics. 23:25712-25719

Using first principles, we theoretically investigate the strain manipulation of the ultrafast spin–flip processes on the Ni@B80 endohedral fullerene by using highly correlated quantum chemical calculations. It is shown that the ultrafast local spin

Spin hall effect in a 2DEG in the presence of magnetic couplings

Autor: Mirco Milletari, Cosimo Gorini, Michael Dzierzawa, Peter Schwab, Roberto Raimondi

It is now well established that the peculiar linear-in-momentum dependence of the Rashba (and of the Dresselhaus) spin-orbit coupling leads to the vanishing of the spin Hall conductivity in the bulk of a two-dimensional electron gas (2DEG). In this p

In this review we discuss the multifaceted problem of spin transport in hydrogenated graphene from a theoretical perspective. The current experimental findings suggest that hydrogenation can either increase or decrease spin lifetimes, which calls for

Spin Regulation on 2D Pd-Fe-Pt Nanomeshes Promotes Fuel Electrooxidations

Autor: Yecan Pi, Xiaolei Wang, Ting Zhu, Xiaoling Luo, Xiaoqing Huang, Cheng Liu, Qi Shao, Youyong Li

Publikováno v: Nano letters. 20(3)

Spin engineering provides a powerful strategy for manipulating the interaction between electrons in the d orbital and oxygen-containing adsorbates, while a little endeavor was performed to understand whether such a strategy can make a prosperous enha

Spin switching via quantum dot spin valves

We develop a theory for spin transport and magnetization dynamics in a quantum dot spin valve, i.e., two magnetic reservoirs coupled to a quantum dot. Our theory is able to take into account effects of strong correlations. We demonstrate that, as a r

Magnetics and spintronics on two-dimensional composite materials of graphene/hexagonal boron nitride

Autor: Mengtao Sun, Fengcai Ma, Xuefeng Xu, Xijiao Mu, Jingang Wang

Publikováno v: Materials Today Physics. 3:93-117

Since its discovery, graphene has become a magnetic electronic device with its unique magnetic properties (weak spin-orbit coupling, longer spin coherence, giant magnetoresistance, and longer spin relaxation time), which make it become the ideal prep

The miniaturization of complementary metal–oxide–semiconductor (CMOS) devices becomes increasingly difficult due to fundamental limitations and the increase of leakage currents. Large research efforts are devoted to find alternative concepts that
