摘要
We have developed magnetic elements for field-writable data input to magnetic domain wall logic circuits. The data input elements allow domain walls to be selectively nucleated while maintaining operation of other types of logic element. Here we show for two data input element designs how their performance is optimized and how each element design requires different operating conditions. Each element design is integrated with a shift register made up of a chain of logical NOT gates. A bitwise delete operation is demonstrated with one of these shift registers by controlling domain wall propagation to bring about selective domain wall pair annihilation.
