Permanent magnets are crucial in modern technology as they allow storing, delivering and converting energy. They are able to transform electrical energy into mechanical and vice versa, which means that improving their performance entails transforming energy in a more efficient and sustainable way. The best magnets are based on rare-earths, however, their criticality has brought forward the realization that it is of great strategic, geographic and socio-economic importance to consider alternative magnets that present a reduced amount (or absence) of rare-earths.

One of the most sought approaches towards this goal consists on constructing composites based on two dissimilar magnetic materials that are coupled at the interface. Particular geometrical arrangements may lead to improvements in the magnetic response; however, sculpting the adequate structure at competitive costs remains a challenge.

In the framework of a European Project (FP7-SMALL-NANOPYME-310516), a low-cost novel approach that improves the performance of magnetic materials has been developed. We are focused on producing improved magnetic materials that retain the advantages of ferrites –availability, sustainability, cost, recyclability- and which have the potential to substitute rare-earth magnets.
