Kjetil Magne Dørheim Hals

Prof. Dr. Hals works within the fields of spintronics and spinmechatronics, where the spin of the electron (and not just the charge) is used to develop novel spin-based devices. Important examples of such devices include magnetic random-access memories, which have revolutionized modern memory technology, as well as quantum computing architectures, high frequency oscillators, spin & charge pumps, nanoscale engines, and reprogrammable magnetic logics that are electrically manipulated by currents. The anticipated application potential of this research is in replacing charge-based electronics with ultra-fast, spin-based, low-power, low-noise devices, which have novel forms of signal transmission.
