16. Chemical Tuning of the Magnetic Interactions in Layer Structures
Sammanfattning : Thin metal films have found their use in many magnetic devices. They form pseudo two-dimensional systems, where the mechanisms for the magnetic interactions between the layers are not completely understood. LÄS MER
17. Magnetic frustration and low-dimensional magnetism : in transition metal fluorophosphates and square-lattice intermetallic compounds
Sammanfattning : 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.

18. Density Functional Theory Applied to Materials for Spintronics
Sammanfattning : The properties of dilute magnetic semiconductors have been studied by combined ab initio, Monte Carlo, and experimental techniques. This class of materials could be very important for future spintronic devices, that offer enriched functionality by making use of both the spin and the charge of the electrons. LÄS MER
19. Collective properties of magnetic mesospins
Sammanfattning : Mesoscopic spin systems consist of an ensemble of lithographically patterned nanomagnetic elements - mesospins. The interactions between the mesospins, can be designed at will by altering their lateral arrangement, enabling the study of collective magnetic order in a wide range of systems. LÄS MER
20. Structure Analysis of a Transient Protein Complex - NMR, X-ray crystallographic and Mass Spectrometric Studies of the Soluble Domains of the Proton-Pump Transhydrogenase from E. coli
Sammanfattning : Interactions between macromolecules in the cell are fundamental to life. However, many interactions are of a transient nature and are as such difficult to study at the atomic level using existing techniques. LÄS MER
