AbstractExternally controlled microswimmers offer prospects for transport in biological research and medical applications. This requires biocompatibility of the swimmers and the possibility to tailor their propulsion mechanisms to the respective low Reynolds number environment. Here, we incorporate low amounts of the biocompatible alloy of iron and platinum (FePt) in its $$\hbox {L1}_{{0}}$$ L1 0 phase in microstructures by a versatile one-step physical vapor deposition process. We show that the hard magnetic properties of $$\hbox {L1}_{{0}}$$ L1 0 FePt are beneficial for the propulsion of helical micropropellers with rotating magnetic fields. Finally, we find that the FePt coatings are catalytically active and also make for Janus microswimmers that can be light-actuated and magnetically guided.
