Illustration of the voltage‐control of the magnetic properties in nanoporous CuNi alloys. Application of a continuous voltage to nanoporous alloys is shown to cause a reduction of coercivity (of about 32%), as shown by Roberto Robles, Josep Nogués, Eva Pellicer, Jordi Sort, and co‐workers, in article number 1701904 . The accumulated electrostatic charges induce changes in the energy bands, decreasing the magnetic effective anisotropy.
