  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. A Comparison of Three Time-stepping Methods for the LLG Equation in Dynamic Micromagnetics

    University essay from Uppsala universitet/Avdelningen för beräkningsvetenskap

    Author : Simon Wredh; Anton Kroner; Tomas Berg; [2017]
    Keywords : LLG equation; Micromagnetism; Implicit midpoint; Midpoint extrapolation; Projection method;

    Abstract : Micromagnetism is the study of magnetic materials on the microscopic length scale (of nano to micrometers), this scale does not take quantum mechanical effects into account, but is small enough to neglect certain macroscopic effects of magnetism in a material. The Landau-Lifshitz-Gilbert (LLG) equation is used within micromagnetism to determine the time evolution of the magnetisation vector field in a ferromagnetic solid. READ MORE

  4. 3. Dynamics of magnetic nanostructures

    University essay from Uppsala universitet/Materialfysik

    Author : Julia Liljestrand; [2016]
    Keywords : Spin ice; Micromagnetism; Simulations;

    Abstract : Magnetic nanostructures provide the opportunity to investigate a number ofmagnetic phenomena, and are of interest for their possible future applicationsin technology. In this project, the ferromagnetic response (FMR) of magnetic nanostructures to an electromagnetic excitation has been investigated using the micromagnetic simulations program Mumax3. READ MORE
