Researchers in the Netherlands developed a device composed of individual Fe atoms that allows for remote detection of spin dynamics. They have characterized the device and used it to detect the presence of spin waves originating from an excitation induced by the scanning tunneling microscope tip several nanometres away; this may be extended to much longer distances. The device contains a memory element that can be consulted seconds after detection, similar in functionality to e.g. a single photon detector. They performed statistical analysis of the responsiveness to remote spin excitations and corroborated the results using basic calculations of the free evolution of coupled quantum spins…read more.
