  1. 1. Out-of-plane Ferromagnetic Resonance (FMR) measurements on magnetic nanoparticle dispersions for biomedical sensor applications

    University essay from Uppsala universitet/Fasta tillståndets fysik

    Author : Markus Back; [2020]
    Keywords : Ferromagnetic; magnetic; resonance; FMR; EPR; nanoparticle; microwave; coplanar; waveguide; cavity; s-parameter; gilbert; damping; gyromagnetic; liquid; biosensor; landau; lifshits; spin; polymer; composites; engineering physics; teknisk fysik; magnetism; ferromagnetisk; vågledare; resonans; mikrovågsteknik; nanopartiklar;

    Abstract : In this master work, we investigated the feasibility of a magnetic resonance measurement technique using magnetic nanoparticle dispersions in both liquid and solid form. The implementation is realised as a coplanar waveguide operating in the frequency range of 0.5 - 20 GHz and an electromagnet producing a static magnetic field of strength up to 1. READ MORE

  3. 2. Improving health literacy of newly arrived refugees : A qualitative assessment of the health-communication method Förstå Mig Rätt within the Swedish civic orientation

    University essay from Uppsala universitet/Internationell mödra- och barnhälsovård (IMCH)

    Author : Helge Drebold; [2020]
    Keywords : Health literacy; health communication; health promotion; teach-back; integration; civic orientation; refugees;

    Abstract : Background: The growing number of migrants, and refugees in particular, can have complex impacts on healthcare systems as they face pressures of responding to new healthcare needs. Refugees report lower levels of self-assessed health and psychological well-being compared to host populations, but paradoxically, many refrains from seeking care although they perceive the need to.

  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

  5. 4. Micromagnetic simulations for the investigation of magnetic vortex array dynamics

    University essay from Uppsala universitet/Materialfysik

    Author : Agne Ciuciulkaite; [2016]
    Keywords : micromagnetic simulations; ferromagnetic resonance; magnetic vortex; permalloy circular islands;

    Abstract : In this work the dynamics of permalloy circular magnetic islands of 225 nm radius and 10 nm thickness arranged into square lattices was investigated employing micromagnetic simulations.The simulations of the vortex magnetization loops and the ferromagnetic resonance (FMR) spectra were carried out using a free micromagnetics simulation software Mumax3.

  6. 5. 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
