Physicists from the Moscow Institute of Physics and Technology, the Russian Quantum Center, joined by colleagues from Saratov State University and Michigan Technological University, have demonstrated new methods for controlling spin waves in nanostructured bismuth iron garnet films via short laser pulses. The approach has potential for applications in energy-efficient information transfer and spin-based quantum computing ...
