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

    Author : Inna Soroka; Roger Wäppling; Björgvin Hjörvarsson; Rudolf Schäfer; Uppsala universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; Materials science; Magnetism; Sputter deposition; Superlattice; Multilayers; Materialvetenskap; Materials science; 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

  2. 2. Multifunctional magnetic materials prepared by Pulsed Laser Deposition

    Author : Sandeep Nagar; Lyuba Belova; K. Venkat Rao; Prashanth Kamath; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Magnetic materials; thin films; pulsed laser depsoition; spintronics; chromites; MgO; NEMS; MEMS;

    Abstract :      Pulsed LASER deposition (PLD) is widely recognized as excellent deposition technique owing to stoichiometric transfer of target material, easy preparation and high quality. Thin films from few nanometers to micrometer regime can be fabricated with equal ease. READ MORE

  3. 3. Local magnetic susceptometry : Visualizing functional properties of novel materials
