The ApNano group has taken part, in collaboration with researchers from the Norwegian University of Science and Technology and from the University of Sydney, in an investigation of magnetically enhanced mechanical stability in self-assembled nanostructures. The results, which have just been published in Advanced Functional Materials, combine Monte Carlo simulations, magnetic characterization and electronic microscopy to conclude a significant increase in cohesive energy from the magnetostatic interactions between magnetite nanocubes assembled in dense superstructures. This increase depends strongly on the size of the assembly. The discovery of this effect opens new possibilities in size-controlled tuning of superstructure properties, thus contributing to the design of next-generation self-assembled materials with simultaneous enhancement of magnetic and mechanical properties.
