In collaboration with the Max Planck Institute for Sustainable Materials, the Dep. of Functional Materials presents a novel approach to simultaneously enhance the magnetic and mechanical properties of rare-earth-free multicomponent magnets. By applying thermomagnetic fields, we accelerate phase decomposition and refine nano lamellar structures that improve coercivity and mechanical strength. This breakthrough opens new possibilities for sustainable, high-performance magnets in energy conversion technologies such as high-speed motors and generators in harsh environments.
