Today's technologically driven society relies on magnetic materials to an extent unimaginable even as recently as 20 years ago. Rare-earth transition-metal intermetallics are among the most important magnetic materials, providing the World's strongest magnet with extensive applications. Despite these impressive technological and commercial developments numerous aspects of rare-earth magnetism remain to be developed and resolved. The two innovative topics we shall research are the critical interplay between the rare-earth and transition-metal sublattices in ternary compounds, enabling us to understand complex compounds, and exploration of a set of quaternary compounds we have recently discovered, thus opening new areas of rare-earth magnetism.

当今技术驱动的社会对磁性材料的依赖程度即使在 20 年前也是难以想象的。稀土过渡金属间化合物是最重要的磁性材料之一，为世界上最强的磁体提供了广泛的应用。尽管有这些令人印象深刻的技术和商业发展，稀土磁性的许多方面仍有待开发和解决。我们要研究的两个创新课题是三元化合物中稀土和过渡金属亚晶格之间的关键相互作用，使我们能够理解复杂的化合物，以及探索我们最近发现的一组四元化合物，从而开辟稀土磁性的新领域。
