Nanoscale spin waves could replace microwave technology in tomorrow's wireless devices, according to some scientists. Now, researchers for the first time have been able to tie together theories with tangible observations. Using a specialized microscope, the team was able to visually express the propagation of spin waves from magnetic nano-contacts (see video). This opens up a potential pathway to replacing microwaves with a smaller, cheaper, and less resource-taxing technology. What's your view?
