  1. 1. Steering system modal analysis

    Master-uppsats, KTH/Teknisk akustik

    Författare :Silvia Milani; [2023]
    Nyckelord :Ride comfort; Steering wheel vibrations; Resonance excitations; Åkkomfort; Rattvibrationer; Resonansexcitationer;

    Sammanfattning : The vehicle manufacturing sector is constantly evolving, and corporations are fully aware of increased consumer expectations for both driver and passenger´s comfort. SCANIA CV AB, as one of the largest Swedish manufacturers of commercial vehicles, has put an emphasis on this area. LÄS MER

  3. 2. Low-dimensional Magnetism in Novel 2D Honeycomb Materials

    Master-uppsats, KTH/Tillämpad fysik

    Författare :Sebastian Johnsen; [2021]
    Nyckelord :Applied physics; Materials physics; Quantum materials; Magnetism; Muons; Neutrons; Tillämpad fysik; Materialfysik; Kvantmaterial; Magnetism; Myoner; Neutroner;

    Sammanfattning : A Kitaev quantum spin liquid is a phase of matter predicted to host excitations that can be used to preform fault-tolerant quantum computation. Though the theoretical prediction of such a state is on firm footing, its realisation in real materials has proven to be elusive. LÄS MER

  4. 3. Transient Dynamics and Core Tunneling in Vertical Spin-Vortex Pairs

    Master-uppsats, KTH/Nanostrukturfysik

    Författare :Milton Persson; [2019]
    Nyckelord :Spin-vortex; ultra fast vortex dynamics; milli-Kelvin temperatures; macroscopic quantum tunneling; Spinnvirvel; ultrasnabb virveldynamik; milli-Kelvin temperaturer; makroskopisk kvanttunnling;

    Sammanfattning : Spin-vortices in vertically spaced pairs of thin elliptical Permalloy nanoparticles are investigated. The two vortex cores with parallel out-of-plane magnetization exhibit a strong monopole-like attraction through the spacer much thinner than the core length, thus forming a bound core-core pair.

  5. 4. Towards a tunable nanometer thick flat lens

    Magister-uppsats, Uppsala universitet/Materialfysik

    Författare :Hugo Laurell; Johan Hillborg; [2018]
    Nyckelord :Metamaterial; COMSOL; Fano resonances; Surface plasmon polariton; Localized surface plasmons; Nanophotonics;

    Sammanfattning : This report examines the cross sections of silver microresonators subjected to an incident light with different polarization. The microresonators had different geometries with and without broken symmetries. LÄS MER

  7. 5. Micromagnetic simulations of magnetization dynamics in iron-palladium nanostructure arrays

    Master-uppsats, Uppsala universitet/Materialfysik

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

    Sammanfattning : 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. LÄS MER
