  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.

  2. 2. Electrical Properties of planar Metal-GdN-Metal junctions for Spintronic Applications

    Master-uppsats, Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Fysiska institutionen

    Författare :Felicia Ullstad; [2015]
    Nyckelord :nitride; gadolinium; spintronic; rare earth nitride; ferromagnetism; ferromagnetic; Semiconductor; Physics and Astronomy;

    Sammanfattning : In this thesis the properties of planar metal-gadolinium nitride-metal junctions have been studied with the aim of establishing ohmic and Schottky contacts to thin polycrystalline films of n-type gadolinium nitride (GdN). GdN is an intrinsic ferromagnetic semiconductor of the rare earth nitride series. LÄS MER

  3. 3. Theoretical study of dilute magnetic semiconductors : Properties of (Ga,Mn)As

    Kandidat-uppsats, Uppsala universitet/Institutionen för fysik och astronomi

    Författare :Maya Staneva; [2010]
    Nyckelord :semiconductor; DMS; spintronics; electronic band structure; magnetiska halvledare; spinntronik;

    Sammanfattning : The dilute magnetic semiconductor (Ga,Mn)As , which is the most interesting and promising material for spintronics applications, has been theoretically studied by using Density Functional Theory. First of all, calculations on GaAs were done and it was found that GaAs is a semiconductor with a direct band gap. LÄS MER
