FIG. 1.

(a) Schematic of the bimagnet system and the misaligned clocking field. (b) The reversed clocking field applied with 5° misalignment. (c) Hysteresis—minor loops in both longitudinal and transverse modes of the bimagnet system. (d) The array magnetic state (only three elements are shown here). (highlighted with yellow dotted arrow) and its antiparallel state with will remain if the reversal field is within its SFW. The two cases marked on the right side indicate that and will stay unchanged.

Image of FIG. 2.
FIG. 2.

(a) The reversal clocking field employed for the array with 5° misalignment. Magnetic states at points B-F are shown below. (b) A—SEM image of the patterned array; B-F—simulated magnetic state and the corresponding MFM image for different steps in (a). As the amplitude of the reversal field decreases, elements will be aligned antiparallel with their neighbor and be stable sequentially from right to left. The magnetization direction is indicated by the color wheel or overlaid arrows. The scale bar stands for 500 nm in (b) A-F.

Image of FIG. 3.
FIG. 3.

(a) and (b) Simulated MQCA logic structures with different inputs using the reversal clocking field. (c) and (d) Control architectures of traditional structure and clocking field. There is no shape tuning and no reversal clocking field in (c) and (d), respectively.
