Published in 2021 at "Nano letters"

DOI: 10.1021/acs.nanolett.1c01607

Abstract: Spin accumulation is generated by passing a charge current through a ferromagnetic layer and sensed by other ferromagnetic layers downstream. Pure spin currents can also be generated in which spin currents flow and are detected… read more here.

Published in 2022 at "Proceedings of the National Academy of Sciences of the United States of America"

DOI: 10.1073/pnas.2116180119

Abstract: Significance In contrast to conventional electronics, spintronics devices exploit the electron spin as an additional degree of freedom. The chirality-induced spin selectivity (CISS) effect, in which chiral molecules act as spin filters in electron transport,… read more here.

Published in 2018 at "Journal of Physics D: Applied Physics"

DOI: 10.1088/1361-6463/aaca89

Abstract: Pure spin currents, i.e. the transport of angular momentum without an accompanying charge current, represent a new, promising avenue in modern spintronics from both a fundamental and an application point of view. Such pure spin… read more here.

Published in 2020 at "Physical Review B"

DOI: 10.1103/physrevb.102.125431

Abstract: We investigate electron spin currents induced optically via plasmonic modes in the Kretschmann configuration. By utilizing the scattering matrix formalism, we take the plasmonic mode coupled to an external laser drive into consideration and calculate… read more here.

Published in 2017 at "Physical Review B"

DOI: 10.1103/physrevb.95.104436

Abstract: In magnets with non-collinear spin configuration the expectation value of the conventionally defined spin current operator contains a contribution which renormalizes an external magnetic field and hence affects only the precessional motion of the spin… read more here.

Published in 2017 at "Physical Review B"

DOI: 10.1103/physrevb.96.054403

Abstract: Starting from the general Berry phase theory of the Dzyaloshinskii-Moriya interaction (DMI) we derive an expression for the linear contribution of the spin-orbit interaction (SOI). Thereby, we show analytically that at the first order in… read more here.
