Invited talk: Spintronics with random spin-orbit coupling by Evgeny Sherman
We are pleased to announce the invited talk given by Evgeny Sherman, Ikerbasque Professor at the University of Basque Country UPV-EHU, entitled “Spintronics with random spin-orbit coupling”.
Spin-orbit coupling is one of the key elements in modern spintronics – the effects of coupled charge and spin dynamics. The coupling strength is usually assumed to be independent of the electron position. Here we consider a realistic spatially random spin-orbit coupling strength produced by an inevitably random distribution of dopant ions and other statistical imperfections. As demonstrated by recent experiments, the spin-orbit coupling is realized as a random function of coordinate correlated on a spatial scale of the order of 10 nm. We will show how to determine theoretically main properties of the random spin-orbit fields such as the characteristic amplitude and the correlation length. We will concentrate on the experimental consequences in prospective elements for applied spintronics, where the effects of disorder are highly nontrivial. By analyzing different regimes of electron transport and spin dynamics, we will discuss the effects of spin relaxation and spin currents in these structures.
The talk will be on November 11th at 11:00.
The event is free and open for everybody, it will be at the Martina Casiano Auditorium and also online via TEAMS with the following link:
