  1. 1. On Some Properties and Applications of Patterned Ferromagnetic Thin Films

    Author : Pierre E. Roy; Peter Svedlindh; Per Nordblad; Jeffrey McCord; Uppsala universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; Materials science; micromagnetics; vortex; spin dynamics; domains; MFM; microwave; patterned; permalloy; Materialvetenskap; Materials science; Teknisk materialvetenskap;

    Abstract : A microwave reflection method has been used to measure the spin excitations corresponding to the translational mode of magnetic vortices in samples containing either one or two vortices. Experimental findings are complemented by micromagnetic simulations. One-vortex systems are investigated in micron-sized circular and elliptical cylinders. READ MORE

  2. 2. Tailored Properties of Ferromagnetic Thin Films

    Abstract : Magnetic thin films and patterned nanostructures have been studied with respect to their magnetic properties using SQUID-magnetometry, magnetic force microscopy, electrical measurements, and micromagnetic calculations. Properties of vortex domain walls, trapped in Permalloy nanowires with artificial constrictions, were investigated experimentally and by numerical calculations. READ MORE
