Heat control in circuits via magnetic nanoswitch - Electronics News

FUTURE computer processors may utilise the heat generated by the circuits to make switching easier or to store data more efficiently. Researchers at Physikalisch-Technische Bundesanstalt (PTB) in Germany have discovered an effect in magnetic tunnel structures which allow thermoelectric voltages in nano-electronic junctions to be controlled. Today, magnetic tunnel structures already occur in various areas of information technology. They are used as magnetic storage cells in non-volatile magnetic memory chips (the so-called "MRAMs" - Magnetic Random Access Memories) or as highly sensitive magnetic sensors to read out the data stored on hard disks. The new effect discovered at PTB will add new applications to the existing ones, allowing the monitoring and control of thermoelectric voltages and currents in highly integrated electronic circuits. Magnetic tunnel structures consi...
