Nanoscale spin-wave circuits based on engineered reconfigurable spin-textures

Information processing technologies that are typically based on electron charges can also theoretically make use of the electric spin. Magnon spintronics can harness quantized spin waves, magnons, as carriers of spin currents in integrated magnonic circuits. The wave character and joule heating-free propagation of spin waves is a promising combination to engineer highly efficient computing platforms with integrated magnonic circuits. While crucial, the realization of nanoscale circuitry is extremely challenging due to the difficulty of tailoring nanoscopic magnetic properties using existing, conventional techniques. Magnonics is therefore a young field of research at the intersection of the study of spin dynamics and nanoscale science and technology.
