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. Simulated lifetime of magnons and short wavelength distortion of magnons in bcc iron and fcc cobalt

   University essay from Materialfysik

   Author : Leo Svenningsson; Sami Freiwat; [2013]
   Keywords : magnon;

   Abstract : The topic of this report is in electron spin dynamics where simulations where made using the UppASD simulations software based on the Landau-Lifshits-Gilbert equation. When many spins act together they form a wavelike movement called a magnon.  It is believed that the magnon can be used as information carrier in next generation of technology. READ MORE
