Reconfigurable single-nanotrack skyrmion logic gates (IMAGE) Science China Press Caption XOR/OR/NAND operations of the reconfigurable nanotrack by turning the switch (a) to idle, (b) to 1 and (c) to 2, respectively. XNOR/NOR/AND functions can be converted from the above logic gates by switching the magnetization of the fixed layer in the magnetic tunnel junction (output-MTJ) and only half of the NAND gate can be used to realize the NOT gate.
