Antiferromagnetic Material's Giant Stride Towards Application

Caption

Fig.2: (a) A schematic diagram of the developed stack structure. (b) The experimental results of current-induced switching of AFM/HM PtMn/Pt structure under applied current JPt in the Pt layer. The reading of the antiferromagnetic states was achieved by measuring the output read resistance (RHall). (c) The stability of recorded states (1 or 0) was investigated by measuring RHall for several hours. The red and blue shaded area corresponds to the electrical recording of the high resistive ("1") or low resistive ("0") states. (d), (e) X-ray magnetic imaging of the PtMn/Pt structure after the application of current pulses. White and black areas of the image indicate regions of opposite magnetic contrast, representing the reversal of the antiferromagnetic order.
