  2. 1. Very thin magnets : X-rays, lasers and spectroscopy

    Author : Jonathan Hunter Dunn; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physics; Fysik; Physics; Fysik; fysik; Physics;

    Abstract : The magnetic properties of transition metal films are investigated using synchrotron based x-ray absorption and x-ray photoelectron spectroscopy. These techniques are elementally selective and may therefore be used, either to probe a specific element in a multicomponent system or, as very sensitive magnetometers. READ MORE

  4. 2. Fabrication and study of inorganic and organic thin film magnets

    Author : Pramod Bhatt; Mats Fahlman; Hans Siegbahn; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physics; electronic; thin films; inorganic magnets; organic magnets; Physics; Fysik;

    Abstract : Thin film magnets are very important for many kinds of electronic devices and play a crucial role to achieve optimum performance. Therefore an intense level of research is going on all around the world to fabricate advanced electronics devices using both new inorganic and organic thin-film magnets. READ MORE

  5. 3. Correlations in Frustrated Magnets : Classical and Quantum Aspects

    Author : Sergei Isakov; Anders Karlhede; Frederic Mila; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physics; Fysik;

    Abstract : In this thesis, we study three different aspects of the physics of frustrated magnets. First, we study the interplay of thermal and quantum fluctuations in the transverse field frustrated Ising model on the triangular lattice. READ MORE

  6. 4. Design, Synthesis And Characterization Of Magnetic Ferrite Nanostructures : Toward Novel Permanent Magnets

    Author : Pierfrancesco Maltoni; Roland Mathieu; Adrian Quesada; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; nanosystems; magnetic interactions; magnetism; ferrites; materials science; Engineering Science with specialization in Solid State Physics; Teknisk fysik med inriktning mot fasta tillståndets fysik;

    Abstract : Magnetic oxide nanoparticles (NPs) may interact with each-other for example via dipolar or superexchange interactions, depending whether they are in direct contact. These interparticle interactions yield both ferro- and/or antiferromagnetic coupling and modify the energy barrier of the magnetic particle, depending upon the strength of the coupling and orientation of the particles.
