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

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

    Sammanfattning : 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. LÄS MER

  3. 2. The interaction of light and magnetism in the TbxCo100-x system

    Författare :Agne Ciuciulkaite; Vassilios Kapaklis; Pablo Maldonado; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; magnetism; rate-earth transition metal alloys; light-magnetism interaction; all-optical switching; Fysik; Physics;

    Sammanfattning : Development of the faster and denser magnetic memory storage elements has been an active area of research since early 20th century. The path of research on magnetization manipulation began with firstly changing the magnetization state of a medium in an external magnetic field, then heating of a medium and magnetizing with a permanent magnet was explored, while the latest efforts have been focused on switching the magnetization only by a polarized laser light.

  4. 3. Dynamics in magnetic metamaterials

    Författare :Agnė Čiučiulkaitė; Vassilios Kapaklis; Gabriella Andersson; Björgvin Hjörvarsson; Will Branford; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Metamaterials are artificially created structures with properties that are not found in nature. They can be tailored to achieve desired response to external excitations such as external electric and magnetic fields, as well as to enhance materials’ optical or magnetic activity. LÄS MER

  5. 4. Functional Interfaces in Epitaxial YBa2Cu3O7-δ with Artificial Grain Boundary Junctions

    Författare :Henrik Pettersson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : The properties of superconducting devices based on grain boundaries in YBa2Cu3O7-δ (YBCO) thin films are determined by the atomic structure of the grain boundary plane. To obtain these devices based on single grain boundaries, biepitaxial fabrication techniques has been used. LÄS MER
