Big changes are about to happen in information technology. Spin waves, the collective spin excitations of magnetic materials, can be used to transmit information. That, provided we learn how to control and manipulate them.
M. Borst et al. at Toeno van der Sar lab, had just published a new breakthrough on this area. They’ve proved that spin waves in a magnetic thin film can be controlled with the use of a superconducting electrode.
As M. Borst explains, “spin waves can be a promising building block for an energy-efficient replacement for electronics”.
We, together with Dr. Borst, prepared this picture for Science to illustrate this new discovery.
