SANS Measurements on Antiferromagnetic Manganese Oxide Nanoparticles
Fundamental research on magnetic nanostructures is an important part of today’s scientific effort in information technology and other fields of current activity. The goal is to reach growing bit density in data storage, which continuously requires miniaturization. Our long term objective is the understanding of magnetic interparticle interactions of anisotropic and composite nanoparticles. The focus of our studies are composite nanoparticles of a ferromagnetic and an antiferromagnetic compound, Iron Platinum and Manganese Oxide, and the exhibited exchange bias in this kind of nanoparticle. Therefore the investigation of spin structure inside these particles is necessary. To achieve a better understanding on the interaction at the interface the determination of spin structure in each compund particle is inevitable. The aim of the proposed project is to determine the spatial magnetization distribution within antiferromagnetic manganese oxide nanoparticles and the required method is therefore SANS.
