Magnetic nanoswitch for thermoelectric voltages

The heat which occurs in tiny computer processors might soon be no longer useless or even a problem. On the contrary: It could be used to switch these processors more easily or to store data more efficiently! These are two of the several potential applications made possible by a discovery made at the Physikalisch-Technische Bundesanstalt (PTB). This so-called “thermoelectric voltage” may well be very interesting – mainly for the use of nano-junctions, i.e.
