  1. 1. Micromagnetic study of spin Hall nano-oscillator arrays and their synchronization dynamics

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Ari Sigurdsson; [2020]
    Nyckelord :spintronics; spin Hall nano-oscillators; spin wave; synchronization; micromagnetic modelling.; spinntronik; spinn-Hall nano-oscillatorer; spinn wave; synkronisering; mikromagnetisk modellering.;

    Sammanfattning : Spintronics is the study of electron spins and their utilization in electronic devices. Within this field, spin-based oscillators have shown promise for mi- crowave signal generation as they can operate at high frequencies, are small in scale and are compatible with modern fabrication techniques.

  4. 4. Interaction of sublevels in gated biased semiconductor nanowires

    Master-uppsats, Linköpings universitet/Teoretisk Fysik

    Författare :Henrik Karlsson; [2016]
    Nyckelord :nanowire; spintronics; lateral spin-orbit coupling; asymmetrical confinement potential; spin polarization;

    Sammanfattning : Mesoscopic devices, such as nano-wires, are of interest for the next step in creating spintronic devices. With the ability to manipulate electrons and their spin, spintronic devices may be realised. To that end the different effects found in low-dimensional devices must be studied and understood.
