  1. 1. 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 : NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; 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.

  2. 2. Formation and Decomposition of Platinum–Thallium Bond, Kinetics and Mechanism. Structural Characterization of Some Metal Cyanides in the Solid State

    Author : Péter Nagy; KTH; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; metal–metal bond; platinum; thallium; kinetics; mechanism; stopped flow; oxidative addition; cyano complexes; edta; redox reaction; metal cyanides; X–ray diffraction; Raman; NMR; mercury; palladium; nickel; one dimensional wire;

    Abstract : The kinetic and mechanistic features of a new series ofplatinum-thallium cyano compounds containing a direct andunsupported by ligands metal-metal bond have been studied insolution, using standard mix–and–measurespectrophotometric technique and stopped–flow method.These reactions are interpreted as oxidative addition of the cspecies to the square planar Pt(CN)42-complex.

  3. 3. The Role of Tetrahedral Building Blocks in Low-Dimensional Oxohalide Materials

    Author : Iwan Zimmermann; Mats Johnsson; Lars Kloo; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Lone-pair elements; crystal structure; low-dimensional compounds; oxohalides; Inorganic Chemistry; oorganisk kemi;

    Abstract : The structural architecture found in low-dimensional materials can lead to a number of interesting physical properties including anisotropic conductivity, magnetic frustration and non-linear optical properties. There is no standard synthesis concept described thus far to apply when searching for new low-dimensional compounds, and therefore control on the design of the new materials is of great importance.

  4. 4. Synthesis and characterization of two- and three-dimensional nanolaminated carbides

    Author : Quanzheng Tao; Johanna Rosén; Per O A Persson; Amit Keren; Linköpings universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP;

    Abstract : This thesis is focused towards the synthesis and characterization of novel nanolaminated materials in primarily bulk (powder) form. Of particular interest is magnetic materials, or laminates that can be used as precursor for two-dimensional (2D) materials. READ MORE

  5. 5. An X-ray Spectroscopic Study of Perovskites Oxides and Halides for Emerging Devices

    Author : Dibya Phuyal; Olof Karis; Manuel Bibes; Uppsala universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; perovskite oxides; halide perovskites; x-ray spectroscopy; electronic structure; Physics with spec. in Atomic; Molecular and Condensed Matter Physics; Fysik med inriktning mot atom- molekyl- och kondenserande materiens fysik;

    Abstract : This thesis investigates the electronic structures on several perovskite oxide and halide materials with a focus on light harvesting applications. The systematic study of the electronic properties of the transition metal oxides and post-transition metal halides is a key point if one is to understand their properties. READ MORE
