1. Theory of Disordered Magnets
Sammanfattning : 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. LÄS MER
2. The paramagnetic Meissner effect
Sammanfattning : The low field dynamics of some high temperature superconductors have been studied experimentally, using SQUID magnetometry. The research has been focused on the so called Paramagnetic Meissner Effect (PME), a phenomenon seen in some high temperature superconducting cuprates. LÄS MER
3. Collective behavior of disordered magnetic systems
Sammanfattning : Magnetic properties of disordered and frustrated magnets have been experimentally investigated. The magnetic systems in focus in this work are spin-glasses and frozen ferrofluids (suspensions of nano-sized magnetic particles). LÄS MER
4. Anisotropic Protein Interactions in Salt Solutions and at Interfaces: Coarse Grained Modeling
Sammanfattning : Anisotropic protein interactions have a strong orientation dependence resulting from an uneven distribution of charged and hydrophobic residues on the protein surface. They play an important role in protein behaviors such as protein association, surface adsorption and phase separation. LÄS MER
5. Amorphous Magnetic Materials : A Versatile Foundation for Tomorrow’s Applications
Sammanfattning : Amorphous magnetic materials exhibit a number of key differentiating properties with respect to crystalline magnets. In some cases, the differences may simply be in the values of macroscopic properties such as saturation magnetization, coercivity, Curie temperature, and electrical conductivity. LÄS MER
