| Outline of Final Research Achievements |
Numerical and experimental studies have been executed to develop a novel logic in memory architecture, where domain walls were utilized as the stored binary information and the logic operation was performed through their interaction with a propagating spin wave.
It was confirmed by micromagnetics simulations that a spin wave phase lag induced with the dynamic interaction between the spin wave and the domain can be applied to logic gate operation. Prototype devices, consist of spin wave propagation truck, generator and inductive detector have been fabricated with the lithographic technique. Logic output ratio exceeding 20 dB was successfully achieved in the micro-structured sample.
