| Description | According to RCUK, economic and societal impact refers to the tangible contribution that outstanding research makes to society and the economy. Such impacts are diverse and can manifest in many ways, including improving the global economic performance of the United Kingdom, enhancing the effectiveness of public services and policy, and elevating the quality of life, health, and creativity. Through our "Picosecond Dynamics of Magnetic Exchange Springs" grant (Exeter-Diamond-Oxford), we have advanced academic research by deepening our understanding of the magnetic exchange interaction within nanostructured materials. This research has facilitated the development of innovative technologies that can solve societal problems. In 2020, we organized research and industrial conclaves (https://blogs.exeter.ac.uk/exspring/team/) that brought together industrialists and international academic leaders to deliberate on the scientific and technological opportunities presented by our research. This event, along with our participation in scientific and public engagement meetings, has raised awareness of exchange springs as a viable alternative to the over-reliance on Chinese permanent magnets for applications such as motors. Furthermore, our research has opened up new possibilities for low-energy data storage solutions that address energy and environmental challenges posed by data storage centers. These achievements were only possible due to the EPSRC funding. The consortium has successfully achieved impact beyond academia by engaging with various stakeholders, including industry and the public. One such engagement activity involved organizing a conclave in 2020, which brought together industrialists and international academic leaders to discuss the scientific and technological opportunities presented by their research. More information about this event can be found at https://blogs.exeter.ac.uk/exspring/team/. Furthermore, the consortium has participated in outreach events, such as the World of Music, Arts, and Dance Festival in 2019, to communicate their research to the general public. To make the science more accessible and engaging, the consortium developed bespoke models of the physical systems, which were demonstrated at events in Exeter, Oxford, and at Diamond. These models were also used for outreach events aimed at families and young children, including the respective Open Days, before the COVID-19 pandemic.
