  1. 1. Micromagnetic Study of Current Induced Domain Wall Motion for Spintronic Synapses

    University essay from Uppsala universitet/Energimaterialens fysik

    Author : Dimitrios-Petros Petropoulos; [2021]
    Keywords : computational physics; micromagnetism; micromagnetic simulations; Mumax3; current induced domain wall motion; domain wall driving; spin current; spin transfer torque; synapse; memristor; Neuromorphic computing; spintronic; brain inspired computing; Permalloy; nanowire; nanostrip; notches;

    Abstract : Neuromorphic computing applications could be made faster and more power efficient by emulating the function of a biological synapse. Non-conventional spintronic devices have been proposed that demonstrate synaptic behavior through domain wall (DW) driving. READ MORE

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

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

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

    Abstract : 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. 3. Micromagnetic simulations of magnetization dynamics in iron-palladium nanostructure arrays

    University essay from Uppsala universitet/Materialfysik

    Author : Agne Ciuciulkaite; [2016]
    Keywords : micromagnetic simulations; magnetization dynamics; iron-palladium circular islands; ferromagnetic resonance;

    Abstract : Previous investigations of FePd circular island arrays have shown the hysteresis-free switching from vortex to collinear magnetic state at high temperatures [1]. This raises interest in the exploration of the temperature and inter-island interaction effect on the magnetization dynamics in this kind of structures. READ MORE
