In article number 1804557 , Danny Porath, Yossi Paltiel, and co‐workers demonstrate imprinting of ferromagnetism on super paramagnetic iron oxide nanoparticles (SPIONs) following asymmetric self‐assembled adsorption of polyalanine chiral molecules. The adsorbed chiral molecules stabilize the magnetization direction of SPIONs at room temperature with a coercive field of about 80 Oe. This procedure allows reduction in size of magnetic memory systems.
