(a) AFM image of the circular chain of magnets. (b) MFM phase image of the structure in ground state. (c) The “0” information is inverted to a “1” after a positive magnetic field pulse and transported one magnet further. (d) MFM image after one clocking cycle, visualizing the proceeding information transport.
Simulation of the coupling flux density . The enlarged image shows the fringing fields in the area of the ANC of the consecutive magnet.
(a) Magnetization state of the last magnet of the chain during 200 clocking cycles. (b) Inset of the first 8 clocking cycles. The plot shows the switching during the applied external clocking field. (c) Inset of the section, in which the only error occurred.
