Society faces an accumulated need to find ways to produce super strong magnets that can fulfill thegrowing demands for green technology products such as compact and efficient generators and motors. Next‐generation magnets could very likely be composite materials built bottom‐up from nanoparticles. However, combining the nanoparticles into a compact magnetic material where all magnetic moments are aligned is an engineering challenge.
We investigate ‐ with nanoparticle‐resolution – principles of assembly processes and particle arrangements that can generate optimal magnetic order in new materials (see e.g.Fig. 1). These studies are enabled by advanced transmission electron microscopy, magnetic modelling and new synthesis protocols.
Examples of magnetic ordering and self‐organization will be given.
