Researchers in the US, Italy and Spain have developed a new technique to write fully reconfigurable magnetic nanopatterns in continuous multilayer films in which the magnetization can be oriented at will. The method allows magnetism to be controlled at the nanoscale in a way that was not possible before, and could be used to fabricate a new generation of computing and sensing devices, such as those based on the propagation of spin waves, for example, instead of the more traditional electric current………
