2. 16. Transmission Electron Microscopy for Characterization of Structures, Interfaces and Magnetic Moments in Magnetic Thin Films and Multilayers

   Author : Hans Lidbaum; Klaus Leifer; Peter Svedlindh; Josef Zweck; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Transmission electron microscopy; TEM; magnetism; multilayer; superlattice; thin films; amorphous metals; electron energy-loss magnetic circular dichroism; EMCD; electron diffraction; Magnetism; Magnetism; Surfaces and interfaces; Ytor och mellanytor; Physics; Fysik; Engineering Science with specialization in Solid State Physics; Teknisk fysik med inriktning mot fasta tillståndets fysik; Materiefysik; Physics of Matter;

   Abstract : Structural characterization is essential for the understanding of the magnetic properties of thin films and multilayers. In this thesis, both crystalline and amorphous thin films and multilayers were analyzed utilizing transmission electron microscopy (TEM). READ MORE

4. 17. Thin Film Synthesis of Nickel Containing Compounds

   Author : Erik Lindahl; Jan-Otto Carlsson; Jens Birch; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Chemical Vapor Deposition; CVD; Atomic Layer Deposition; ALD; Nickel nitride; Nickel oxide; Nickel; Epitaxy; multilayer; Thin film; Inorganic chemistry; Oorganisk kemi; Inorganic Chemistry; Oorganisk kemi;

   Abstract : Most electrical, magnetic or optical devices are today based on several, usually extremely thin layers of different materials.  In this thesis chemical synthesis processes have been developed for growth of less stable and metastable layers, and even multilayers, of nickel containing compounds.

5. 18. Spin Dynamics and Magnetic Multilayers

   Author : Björn Skubic; Olle Eriksson; Lars Nordström; Mark D. Stiles; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physics; magnetism; electronic structure; density functional theory; spin dynamics; spin-transfer torque; spin-density wave; multilayer; interface structure; Fysik;

   Abstract : Theoretical studies based on first-principles theory are presented for a number of different magnetic systems. The first part of the thesis concerns spin dynamics and the second part concerns properties of magnetic multilayers. The theoretical treatment is based on electronic structure calculations performed by means of density functional theory. READ MORE

6. 19. Adsorption of biopolymers and their layer-by-layer assemblies on hydrophilic surfaces

   Author : Maria Lundin; Eva Blomberg; Thomas Arnebrant; KTH; []
