磁性量子元胞自动机拐角结构的理论模拟和实验
Theoretical study and experimentation of magnetic quantum-dot cellular automata corner structure
摘要
Abstract
Magnetic quantum-dot cellular automata （MQCA） comer structure consists of both ferromagnetic coupling and anti-ferromagnetic coupling. Signal propagation of comer structure for magnetic material Fe is theoretically investigated by applying an external clocking field method. Magnetization evolution image on signal propagation of the comer is presented by micromagnetic simulation; it is shown that Fe nanomagnets can ensure stable switching of comer including two kinds of lengthy coupling. The proposed comer structure is then fabricated by electron beam lithography, thermal evaporation and lift-off technologies. Scanning electron microscopy and magnetic force microscopy measurement results demonstrate perfect pattern and correct signal propagation of two types of coupling.关键词
