  2. 1. First-principles theory of electrically-induced spin and orbital magnetization

    Author : Leandro Salemi; Peter M. Oppeneer; Yuriy Mokrousov; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Spin-orbit torque; spin Hall effect; Rashba-Edelstein effect; spin Nernst effect; relativistic DFT; spin-orbitronics;

    Abstract : Spin-orbit torques (SOTs) have emerged recently as practical tools to control the magnetization in spintronic devices, but it is debated what the underlying fundamental processes are that enable fast and energy-efficient magnetization switching.In this thesis, we investigate theoretically possible means of controlling magnetization in magnetic materials and heterostructures.

  4. 2. Graphene spin circuits and spin-orbit phenomena in van der Waals heterostructures with topological insulators

    Author : Dmitrii Khokhriakov; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Graphene; Spin-charge conversion; Topological insulator; Spintronics; Proximity effect; Van der Waals heterostructures;

    Abstract : Spintronics offers an alternative approach to conventional charge-based information processing by using the electron spin for next-generation non-volatile memory and logic technologies. To realize such technologies, it is necessary to develop spin-polarized current sources, spin interconnects, charge-to-spin conversion processes, and gate-tunable spintronic functionalities.

  5. 3. Interactions on the edge of a quantum spin Hall insulator

    Author : Anders Ström; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; topological insulators; quantum spin Hall effect; low-dimensional physics; bosonization; renormalization group;

    Abstract : Effects from electron-electron interactions on the edge of a quantum spin Hall insulator are studied using bosonisation and renormalisation group methods. First, a quantum spin Hall device with a point contact connecting two of its edges is considered. READ MORE
