In article number 1604532 Stefan M. Schiller, Helmut Cölfen, and co‐workers apply the toroidal protein Hcp1 to connect cobalt ferrite nanoparticles (NPs). The cover illustrates the directed molecular assembly and ferrimagnetic coupling of NPs into biohybrid nanofibers. The fibers exhibit enhanced saturation (+28%) and remanence magnetization (+38%) and a coercive field (+12%) comparable to high‐end Nd 2 Fe 14 B bulk magnets at 2 K.
