1. Spin ice and demagnetising theory
Abstract : Frustration, or the inability to simultaneously minimise all local interactions is, a phenomenon occurring in a broad number of physical systems. We will in this thesis focus on a class of frustrated ferromagnetic materials called spin ices and how both numerical and experimental techniques can be used to understand their properties. READ MORE

2. Spin ice under uniaxial pressure and magnetic frustration in garnets
Abstract : Frustration is the inability to simultaneously satisfy all interactions. The interest in magnetic frustration has grown during the last decades. The research has among other findings been promoted by the discovery of spin ice which is a frustrated magnetic compound with an exotic ground state and unusual excitations. READ MORE

3. Tailoring the magnetic order in mesoscopic spin systems
Abstract : Mesoscopic spin systems can be designed and fabricated using modern nano-fabrication techniques. These systems can contain large numbers of patterned ferromagnetic elements, for which the shape will generally determine their effective mesospin dimensionality. READ MORE

4. Ice out of Fire : Ice and cloud condensation nucleation of aerosol particles emitted from controlled soot generation and combustion of renewable fuels
Abstract : Aerosol particles, small solid or liquid particles suspended in a gas, are found everywhere in the atmosphere. Air pollution from such particles, mainly soot from combustion-derived activity is a leading cause of premature deaths in the world and have a large effect on the climate. READ MORE

5. Collective properties of magnetic mesospins
Abstract : 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. READ MORE
