Exchange-coupled nanowire-nanoplatelet composites for high-performance sustainable magnets

Objective

In the MAGWIRE project, we will explore the fundamental mechanisms, optimize the performance and upscale the synthetic protocol for the next generation of sustainable high-performance nanocomposite permanent magnets. The project will combine and exploit the key individual expertises of Dr. Matilde Saura Muzquiz (experienced researcher) in the synthesis and structural/magnetic characterization of nanostructured ferrite magnets, and of Prof. Lucas Perez (project supervisor) in the field of nanomagnetism and nanowires synthesis/characterization. The research will build on considerable recent improvements in the performance of strontium hexaferrite magnets achieved through crystal engineering (Ca and Al-doping) and bottom-up nanostructuring (size and morphology control), as well as on promising preliminary results for hexaferrite-nanowire magnetic composites. In MAGWIRE we will develop a novel high-performance exchange-spring nanocomposite magnetic material based on a synergistic nanoscale combination of high-coercivity platelet-shaped Sr1-xCaxFe12-yAlyO19 nanoparticles and high-magnetization FexCo1-x nanowires. The anisotropic shape (plates and wires) of the constituent nanoscale components will drive an inherent self-induced alignment, which will further improve performance. In addition, we will establish scalable synthesis routes based on a fundamental understanding of the mechanisms in play, that will be elucidated by in situ synchrotron X-ray scattering investigations of the nanoplatelet and nanowire formation.
