4. 2. 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

5. 3. Electronic and Geometric Structure of Phthalocyanines on Metals

   Author : Masumeh-Nina Shariati; Maria Novella Piancastelli; Carla Puglia; Kajsa Uvdal; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; monolayer; multilayer; metal-free phthalocyanine; metal phthalocyanine; interaction; intermolecular; adsorbate-substrate; XPS; XAS; STM; DFT; alkali; metallization;

   Abstract : Adsorption of monolayers and multilayers of metal-free and metal phthalocyanines molecules on metal surfaces has been investigated using complementary microscopic and synchrotron-based spectroscopic techniques. It was observed by STM measurements that at monolayer coverage the adsorption direction of the metal-free phthalocyanine molecules with respect to the gold surface vary as a function of temperature, i.
