 E-Mail IMAGE: Fig. 1: A single laser pulse of appropriate intensity can create random skyrmion patterns with a density defined by an external magnetic field (thin arrows). This scheme of laser writing. view more  Credit: MBI Smaller, faster, more energy-efficient: future requirements to computing and data storage are hard to fulfill and alternative concepts are continuously explored. Small magnetic textures, so-called skyrmions, may become an ingredient in novel memory and logic devices. In order to be considered for technological application, however, fast and energy-efficient control of these nanometer-sized skyrmions is required. Magnetic skyrmions are particle-like magnetization patches that form as very small swirls in an otherwise uniformly magnetized material. In particular ferromagnetic thin films, skyrmions are stable at room temperature, with diameters down to the ten-nanometer range. It is known that skyrmions can be created and moved by short pulses of ele
