  4. 2. Magnetism and Structure of Thin 3d Transition Metal Films : XMCD and EXAFS using Polarized Soft X-Rays

    Author : Anders Hahlin; Dimitri Arvanitis; Olof Karis; Claus Schneider; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physics; thin film; xmcd; exafs; anisotropy; coherence; circular polarization; magnetism; Fe; Co; Ag; Fysik; Physics; Fysik; Fysik; Physics;

    Abstract : In this Thesis the magnetic and structural properties of thin epitaxial Fe, Co, and Ni films are discussed. Some of the in-situ prepared samples were used to characterize the degree of circular polarization of the newly installed beamline D1011 at MAX-lab. READ MORE

  5. 3. Magnetic properties of hard-soft amorphous nanolaminates

    Author : Parul Rani; Gabriella Andersson; Petra Jönsson; Kostas Sarakinos; Erik Wahlström; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Amorphous Thin Film; Soft Hard Multilayers; Combinatorial Sputtering; Magnetism; Rigid-Exchange coupling; First-Order Reversal Curve; Fysik; Physics;

    Abstract : Amorphous magnetic thin film heterostructures and multilayers are often used in data storage as well as spintronic devices. Spintronics will help the next generation of nano-electronic devices to increase their memory and processing power and reduce their power consumption. READ MORE

  6. 4. The character of magnetic records of deformed soft sediments with emphasis on liquefaction structures

    Author : Guangyu Sun; Nils Axel Mörner; Don Tarling; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; magnetism; sediments; deformation; Earth sciences; Geovetenskap;

    Abstract : In this thesis the characteristics of magnetic records in deformed soft sediments during postglacial time in Sweden are studied. Magnetic records refer in this study to magnetic remanence (NRM and ChRM) and susceptibility, including its anisotropy (AMS). READ MORE

  7. 5. Magnetic frustration and low-dimensional magnetism : in transition metal fluorophosphates and square-lattice intermetallic compounds

    Author : Stefanie Siebeneichler; Anja-Verena Mudring; Ulrich Häussermann; Sven Lidin; Kenneth R. Poeppelmeier; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; magnetic frustration; low-dimensional magnetism; ionothermal synthesis; powder neutron diffraction; fluorophosphates; intermetallics; Physical Chemistry; fysikalisk kemi;

    Abstract : Solids can display a variety of vastly different magnetic properties. Besides the generally well known ferromagnets, antiferromagnets with their antiparallel arrangements of magnetic moments can exhibit a wide range of complex magnetic behavior such as magnetic frustration or low-dimensional antiferromagnetism.
