Description
Three-dimensional magnetic systems promise significant opportunities for applications as well as new functionalities. Two main challenges concerning their experimental investigation have been addressed, namely the fabrication of three-dimensional magnetic architectures, and the characterisation of three-dimensional magnetisation configurations. In particular, an artificial magnetic buckyball was fabricated, and a detailed characterisation of the structural and elemental properties performed. In addition, hard X-ray magnetic tomography was developed and the complex magnetic configuration within the bulk of a micropillar was determined. The nanofabrication and characterisation techniques developed in this thesis provide a basis for future investigations of a wide variety of three-dimensional magnetic systems.
