  1. 1. Magnetic Heterostructures The Effect of Compositional Modulation on Magnetic Properties

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Inna Soroka; Uppsala universitet.; [2005]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; Magnetism; Sputter deposition; Superlattice; Multilayers; Materialvetenskap; TECHNOLOGY Materials science; TEKNIKVETENSKAP Teknisk materialvetenskap;

    Abstract : The effect of compositional modulation on structural and magnetic properties of magnetic heterostructures was explored. The systems under focus were ferromagnetic superlattices Fe81Ni19/Co, metal-insulator multilayers Al2O3/Ni81Fe19, nanoparticles and artificial multilayered pillars. READ MORE
