  We present an application of a high-throughput search of new rare-earth free
permanent magnets focusing on 3d-5d transition metal compounds. The search
involved a part of the ICSD database (international crystallographic structural
database), together with tailored search criteria and electronic structure
calculations of magnetic properties. Our results suggest that it possible to
find candidates for rare-earth free permanent magnets using a
data-mining/data-filtering approach. The most promising candidates identified
here are Pt$_2$FeNi, Pt$_2$FeCu, and W$_2$FeB$_2$. We suggest these materials
to be a good platform for further investigations in the search of novel
rare-earth free permanent magnets.
