  2. 1. Impedance of Soft Magnetic Multilayers : Application to GHz Thin Film Inductors

    Author : Andrey Gromov; KTH; []
    Keywords : inductor; impedance; magnetic; eddy currents; FMR;

    Abstract : A theoretical approach to calculating impedance of metallicmagnetic/conductor layered structures is developed. Thefrequency range considered extends to the ferromagneticresonance region of soft magnetic films (of the order of 1GHz). READ MORE

  5. 3. Amorphous Magnetic Materials : A Versatile Foundation for Tomorrow’s Applications

    Author : Sebastian George; Gabriella Andersson; Björgvin Hjörvarsson; Fridrik Magnus; Elizabeth Blackburn; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Amorphous; Magnetism; Rare Earth; Transition Metal; RE-TM; Thin Film; TbCo; SmCo; FeZr; CoFeZr;

    Abstract : Amorphous magnetic materials exhibit a number of key differentiating properties with respect to crystalline magnets. In some cases, the differences may simply be in the values of macroscopic properties such as saturation magnetization, coercivity, Curie temperature, and electrical conductivity. READ MORE

  6. 4. The Importance of Controlling Composition to Tailor the Properties of Magnetic Thin Films

    Author : Andreas Frisk; Gabriella Andersson; Tomas Nyberg; Erik Johansson; Sarah Thompson; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; FeNi; L10; X-ray diffraction; magnetic anisotropy; magnetron sputtering; thin film; permanent magnets; combinatorial materials science; amorphous materials; magnetic properties of thin films; chemical order; Physics with spec. in Atomic; Molecular and Condensed Matter Physics; Fysik med inriktning mot atom- molekyl- och kondenserande materiens fysik;

    Abstract : Many physical properties, for example structural or magnetic, of a material are directly dependent on elemental composition. Tailoring of properties through highly accurate composition control is possible in thin films. This work exemplifies such tailoring. READ MORE

  7. 5. Metallic Amorphous Thin Films and Heterostructures with Tunable Magnetic Properties
