  2. 1. Magnetic Ordering in Layered Magnets

    Author : Moreno Marcellini; Björgvin Hjörvarsson; Roger C.C Ward; Uppsala universitet; []
    Keywords : Physics; Magnetic thin films and superlattices; Magnetic phase transitions; Polarized neutron reflectometry; Fysik;

    Abstract : The preparation of layered magnets needs the knowledge of growth techniques which are focused on the growth of Fe/V(001) superlattices. Such films have been structurally investigated by X-rays reflectivity and diffraction. READ MORE

  4. 2. Mössbauer spectroscopy on selectred magnetic compounds

    Author : Beata Kalska-Szostko; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physics; Magnetic multilayers; transition metal compounds; Mössbauer spectroscopy; magnetic ordering; crystal structure; Fysik; Physics; Fysik; fysik; Physics;

    Abstract : The applications of magnetic materials are related to their magnetic and crystal structure as well as electronic properties. In this thesis, mainly experimental methods have been focussed on novel materials and bulk materials. READ MORE

  5. 3. Materials for Magnetic Recording Applications

    Author : Till Burkert; Olle Eriksson; Lars Nordström; Stefan Blügel; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physics; magnetic materials; magnetic anisotropy; saturation magnetization; magnetic data storage; superlattice; hydrogen; density functional theory; first-principles calculations; two-dimensional magnetism; FP-LMTO; EXAFS; MOKE; Fysik; Physics; Fysik;

    Abstract : In the first part of this work, the influence of hydrogen on the structural and magnetic properties of Fe/V(001) superlattices was studied. The local structure of the vanadium-hydride layers was determined by extended x-ray absorption fine structure (EXAFS) measurements. READ MORE

  6. 4. Magnetic ordering and crystal structure in selected transition- metal compounds

    Author : Hui-Ping Liu; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Chemistry; transition-metal compounds; magnetic ordering; crystal structure; magneticstructure; neutron diffraction; Kemi; Chemistry; Kemi; Inorganic Chemistry; oorganisk kemi;

    Abstract : Applications of magnetic materials are inherently related to their crystal, magnetic and electronic structures. In this thesis, experimental and theoretical methods have been focused on magnetic bulk materials from novel chemical synthesis, to X-ray diffraction for initial phase characterisation, and crystal and magnetic structure studies to explain their complex magnetic properties.

  7. 5. Tunable Magnetic Properties of Transition Metal Compounds

    Author : Solveig Felton; Per Nordblad; Peter Svedlindh; John Chapman; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Magnetic properties; Transition metal compounds; Magnetic structure; Domain structure; SQUID-magnetometry; MFM; Magnetism; Magnetism;

    Abstract : The magnetic properties of transition metal compounds have been studied using SQUID-magnetometry, magnetic force microscopy and Lorentz transmission electron microscopy. New magnetic materials have been found and their magnetic properties have been determined. How the magnetic properties of a material can be changed through e.g. READ MORE
