1. Magnetic Heterostructures : The Effect of Compositional Modulation on Magnetic Properties
Sammanfattning : 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. LÄS MER
2. Fundamental Properties of Functional Magnetic Materials
Sammanfattning : Magnetic properties of powders, thin films and single crystals have been investigated using magnetometry methods. This thesis provides analysis and conclusions that are supported by the results obtained from spectroscopic and diffraction measurements as well as from theoretical calculations. LÄS MER
3. Magnetic Multicore Nanoparticles: Magnetic Properties and Applications
Sammanfattning : .... LÄS MER
4. Modulating magnetic interactions : in metamaterials and amorphous alloys
Sammanfattning : This thesis is focused on exploring and modulating magnetic interactions in metamaterials and amorphous alloys along one-, two-, and three-dimensions. First, thin films of alternating Fe and MgO are adapted to modulate magnetic interactions along one dimension. LÄS MER
5. Magnetic Refrigeration for Near Room-Temperature Applications
Sammanfattning : Refrigeration plays a crucial role in many different sectors and consumes about 17% of the electricity produced globally. This significant energy consumption implies large share of refrigeration in primary energy consumption and other environmental impacts. LÄS MER
