  1. 1. Magnetization dynamics in bistable systems

    Kandidat-uppsats, Uppsala universitet/Materialfysik

    Författare :Sven Backlund; [2023]
    Nyckelord :magnetism; magneto-optics; magnetization dynamics;

    Sammanfattning : The magnetization dynamics in ferromagnetic materials will depend on the specific shape of the system’s energy landscape. In most systems, the energy landscapes can be approximated as paraboloids, resulting in a typical ellipti- cal precession of the magnetization. LÄS MER

  3. 2. Photoluminescence Mapping of Erbium Doped Lithium Niobate

    Master-uppsats, KTH/Tillämpad fysik

    Författare :Chuanshi Xie; [2023]
    Nyckelord :Automotive mapping; Erbium emitters; Ion implantation; Lithium niobate on insulator; photoluminescence microscopy; Automatisk kartläggning; Erbium fotonemitterare; Jonimplantation; Litiumniobat på isolator; fotoluminiscensmikroskopi.;

    Sammanfattning : Lithium niobate (LiNbO3) is a human-made crystalline which is widely used in modern photonics due to its useful properties. In recent years, there has been significant progress in the development of lithium niobate on insulator (LNOI) technology, realizing a fully functional photonic integrated circuits, thanks to its capabilities in both electro-optics and second-order optical nonlinearity.

  4. 3. Improving polarizing neutron optics by introducing 11B4C as interlayers

    Master-uppsats, Linköpings universitet/Tunnfilmsfysik

    Författare :Martin Falk; [2023]
    Nyckelord :Thin film multilayers; Neutron optics; Neutron polarization;

    Sammanfattning : In this report, the effects of adding 11B4C as interlayers into Fe/Si multilayers is studied. Fe/Si multilayers are commonly used for neutron polarization at large research facilities, and improving the polarizing properties would improve their efficiency. LÄS MER

  5. 4. Goniochromatic Gradients : Dichroic Color, Thin-Film Optics and Artificial Light

    Magister-uppsats, KTH/Ljusdesign

    Författare :Erik Axel Eggeling; [2018]
    Nyckelord :color; gradient; dichroic filter; dichroism; goniochromatism; goniochromatic gradient; optics; artificial light; color filter; colour; colour filter; thin-film optics; architectural lighting; colored light; coloured light; architectural lighting design; light art;

    Sammanfattning : This thesis is about the multicolored gradients seen when using certain dichroic color lters with artificial light. As of now, this phenomenon lacks a unambiguous descriptor, and “Goniochromatic Gradient” is proposed. LÄS MER
