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. Theoretical study of dilute magnetic semiconductors : Properties of (Ga,Mn)As

   University essay from Institutionen för fysik och astronomi

   Author : Maya Staneva; [2010]
   Keywords : semiconductor; DMS; spintronics; electronic band structure; magnetiska halvledare; spinntronik;

   Abstract : The dilute magnetic semiconductor (Ga,Mn)As , which is the most interesting and promising material for spintronics applications, has been theoretically studied by using Density Functional Theory. First of all, calculations on GaAs were done and it was found that GaAs is a semiconductor with a direct band gap. READ MORE
