Magnetic memory filmed in slow motion by Scientists

The scientists at DESY (Deutsches Elektronen-Synchrotron) used high-speed photography to film one of the candidates for the magnetic data storage devices of the future in action. The film was taken using an X-ray microscope and shows magnetic vortices being formed in ultrafast memory cells. Their work, which has been reported by the scientists surrounding Dr. Philipp…… Continue reading Magnetic memory filmed in slow motion by Scientists
