1. 16. Tailoring Properties of Materials at the Nanoscale

   Författare :Hossein Raanaei; Björgvin Hjörvarsson; Igor A. Abrikosov; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Multilayers; magnetic anysotropy; amorphous materials; Magnetism; Magnetism; Materiefysik; Physics of Matter;

   Sammanfattning : The knowledge of growth and characterizing techniques is essential for the preparation of high quality thin films and multilayers. Here, structural properties have been investigated by X-ray reflectivity, X-ray diffraction, and transmission electron microscopy while the composition was determined by Rutherford backscattering spectrometry.

3. 17. Functional Metallic Glasses

   Författare :Ansar Masood; Lyubov Belova; K. Venkat Rao; Lars Arnberg; KTH; []
   Nyckelord :Bulk Metallic glasses; glass forming ability; soft magnetism; thin films; magnetic properties; magnetic hardening; plasticity; biocompatibility;

   Sammanfattning : For decades, Metallic Glass, with its isotropic featureless structure while exhibiting outstanding mechanical properties was possible only at a high rate of quenching and with at least one dimension in the submicron regime.  This limitation was overcome with the discovery of Bulk Metallic glasses, BMGs, containing three or more elements following the additional two empirical rules of optimum geometric size differences and negative energy of mixing among the constituent elements.

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

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

   Sammanfattning : 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. LÄS MER

5. 19. Cantor-Alloy-Based Multicomponent Nitride Thin Films

   Författare :Smita Gangaprasad Rao; Per Eklund; Arnaud Le Febvrier; Yutao Pei; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Thin films; Multicomponent alloys; Magnetron sputtering;

   Sammanfattning : In this Thesis, I have investigated multicomponent alloy based thin films synthesized by magnetron sputtering. The studies in the thesis are centered around the phase diagram of the CrFeCoNi nitrogen containing system. LÄS MER
