Matilde Saura Múzquiz

During her studies, Matilde Saura-Múzquiz has investigated the relationship between the structure and the magnetic properties of hexaferrite magnets at the atomic-, nano- and microstructural levels. More specifically, Matilde has developed a bottom-up nanostructuring approach for production of high performance strontium hexaferrite magnets, based on the supercritical hydrothermal flow synthesis of SrFe12O19 nanoparticles and subsequent compaction into bulk magnets by spark plasma sintering. The research conducted by Matilde illustrates how nanostructuring can be employed to tune and optimize the properties of hexaferrite-based magnets. Furthermore, the research findings emphasize the necessity for in-depth characterization. Understanding the relationship between synthesis methods, structural characteristics and physical properties is crucial in order to design better magnetic materials.

The PhD degree was completed at iNANO and the Department of Chemistry, Science and Technology, Aarhus University.
