Future information technologies: Nanoscale heat transport under the microscope

(Helmholtz-Zentrum Berlin für Materialien und Energie) Researchers from Helmholtz-Zentrum Berlin (HZB) and University of Potsdam has investigated heat transport in a model system comprising nanometre-thin metallic and magnetic layers. Similar systems are candidates for future high-efficiency data storage devices that can be locally heated and rewritten by laser pulses (Heat-Assisted Magnetic Recording). Measurements taken with extremely short X-ray pulses have shown that the heat is distributed a hundred times slower than expected. The results are published in Nature Communications.
