  1. 1. Theory of Disordered Magnets

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Oleg E. Peil; Uppsala universitet.; [2009]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; disordered alloys; magnetic alloys; spin glasses; ab initio calculations; Monte Carlo methods; NATURAL SCIENCES Physics; NATURVETENSKAP Fysik;

    Abstract : Studying magnetic properties of disordered alloys is important both for the understanding of phase transformations in alloys and from the point of view of fundamental issues of magnetism in solids. Disorder in a magnetic system can result in unconventional magnetic structures, such as spin glass, which have rather peculiar features. READ MORE

    Abstract : We are compounded entities, given life by a complex molecular machinery. When studying these molecules we have to make sense of a diverse set of dynamical nanostructures with wast and intricate patterns of interactions. READ MORE

  3. 3. Local structure in disordered materials studied by neutron scattering and RMC modelling

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Abstract : Different disordered materials are becoming more and more important in various technological applications. There is a need to improve our detailed understanding of the local structure of such materials and how the atomic structure is related to macroscopic physical properties. READ MORE

  4. 4. Disordered Icosahedral Boron-Rich Solids A Theoretical Study of Thermodynamic Stability and Properties

    University dissertation from Linköping : Linköping University Electronic Press

    Author : Annop Ektarawong; Linköpings universitet.; Linköpings universitet.; [2017]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Icosahedral boron-rich solids; Boron carbide; Configurational disorder; First-principles calculations; Thermodynamic stability; Superatom-special quasirandom structure;

    Abstract : This thesis is a theoretical study of configurational disorder in icosahedral boron-rich solids, in particular boron carbide, including also the development of a methodological framework for treating configurational disorder in such materials, namely superatom-special quasirandom structure (SA-SQS). In terms of its practical implementations, the SA-SQS method is demonstrated to be capable of efficiently modeling configurational disorder in icosahedral boron-rich solids, whiles the thermodynamic stability as well as the properties of the configurationally disordered icosahedral boron-rich solids, modeled from the SA-SQS method, can be directly investigated, using the density functional theory (DFT).
