1. Magnetic Heterostructures : The Effect of Compositional Modulation on Magnetic Properties
Abstract : The effect of compositional modulation on structural and magnetic properties of magnetic heterostructures was explored. The systems under focus were ferromagnetic superlattices Fe81Ni19/Co, metal-insulator multilayers Al2O3/Ni81Fe19, nanoparticles and artificial multilayered pillars. READ MORE

2. Tunable Magnetic Properties of Transition Metal Compounds
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

3. Local magnetic susceptometry : Visualizing functional properties of novel materials
Abstract : One of the rapidly growing instrumentation technologies of late has been Surface Probe Microscopy. Since the award of the Nobel Prize in 1986, this form of instrumentation has expanded into various fascinating forms and is successfully enabling investigations at a nano-scale. READ MORE

4. Tailored Properties of Ferromagnetic Thin Films
Abstract : Magnetic thin films and patterned nanostructures have been studied with respect to their magnetic properties using SQUID-magnetometry, magnetic force microscopy, electrical measurements, and micromagnetic calculations. Properties of vortex domain walls, trapped in Permalloy nanowires with artificial constrictions, were investigated experimentally and by numerical calculations. READ MORE

5. Designing order with long-range interactions in mesoscopic magnetic chains
Abstract : This thesis investigates how the low-energy magnetic configuration of a mesoscopic chain can be tuned by geometrical modifications. The magnetic arrays made by single-domain stadium shaped elements positioned side-by-side were fabricated by patterning into a sputtered ferromagnetic thin film. READ MORE
