*Due to ongoing occasional technical problems taking card payments, we are temporarily using EventBrite to register delegates. A VAT invoice will be issued by EventBrite for any card payments, and EventBrite will issue an invoice for payment by other means. We hope to have the problems fully recitified in the near future.

If you don’t want to use EventBrite, please email me at astewart@ukmagsoc.org, and I can register you for the conference and create an invoice manually – but note we can’t take card payments using this method, only bank transfers.

High Throughput Methods for Functional Magnetic Materials Design
by Heike C Herper of Division of Materials Theory Department of Physics and Astronomy, Uppsala University

To fight global warming and to increase independence from external fuel supplies green energy applications have moved in the research focus. Magnetic materials play a key role in many of these applications, such as electric transportation, wind power generation, or the more recently discussed magnetocaloric refrigeration. The increasing interest in environmentally friendly technologies has triggered the search for new magnetic materials being ecologically and economically superior to the currently existing rare-earth magnetic materials. Computational design has been proven to be a powerful tool for this purpose. In the studies presented here, we combine big data searches and high throughput calculations to identify new candidates for permanent magnets and magnetocaloric applications. The focus is on materials which do not contain heavy rare-earth or expensive 5d elements. Starting from a pool of about existing 1000 phases we apply a combination of filters to extract possible candidates for new permanent magnets or magnetic refrigeration. Phases which pass all filter criteria are investigated in detail using a combination of first principles electronic structure methods and thermodynamic modelling [1,2]. Regarding new permanent magnets a promising example has been found and successfully synthesised showing the characteristics of a good permanent magnet [3].

Materials Informatics for the Design of Rare-Earth Reduced Permanent Magnets
by Thomas Schrefl of Christian Doppler Laboratory, University for Continuing Education Krems

High-performance magnets are essential for green technologies. However, these magnets contain a high fraction of critical elements. The transition to carbon free society may lead to a shortage of light and heavy rare-earth elements. In Europe, the additional Dy and Nd consumption in renewables and e-mobility alone in 2050 is 12 and 4 times higher, respectively, than current consumption in all applications [1]. To mitigate supply risks, heavy-rare-earth-free and Nd-substituted magnets are being developed. Materials informatics, combining available data from experiments and computer simulations, opens new possibilities for permanent magnet design and critical element reduction. Permanent magnets can be optimized by considering chemical composition, microstructure, material cost and magnetic performance simultaneously. Machine learning is a tool for the inverse design of permanent magnets. The desired target properties are the starting point for material optimization. For example, we want to make a magnet with a specific coercive field at the magnet's operating temperature and a predefined mixture of chemical elements. Using the power of machine learning-based materials design, we quickly obtain answer to design questions based on all available information ranging from experimental databases to data from ab-initio and micromagnetic simulations. An interactive dashboard for magnet design provides chemical compositions and granular structure of candidate materials that match the desired properties.

Evaluating the impact of magnetic material selection through multi-disciplinary design optimization
by Ruud Sprangers of Punch Power Train

The vision of Punch Powertrain is to provide powertrains that drive a sustainable world. This vision includes a strong focus on electrification and electric drives combined with an optimal use of magnetic material. To design our next-generation of innovative and affordable electric powertrains, the availability of a multi-disciplinary design optimization platform is of key importance. With this platform, Punch Powertrain is able to make trade-offs between a multitude of design criteria, including performance, cost, efficiency, thermals, structural integrity and NVH. For a given set of design requirements and constraints, Pareto-fronts can be generated and explored to find the most suitable solution(s). This approach has enabled Punch Powertrain to fully optimize the usage of magnetic material via in-depth characterization and comparison of Pareto-fronts generated for various magnetic materials to study their impact on the optimal design of an electric machine. During the presentation, the results of such a comparative study will be presented and discussed.
