| Outline of Final Research Achievements |
In this study, we proposed NAND/NOR gates based on a three dimensional magnetic quantum cellular automata (3D-MQCA). The 3D-MQCA NAND/NOR gates were composed of nanodots with magnetic multilayer. The MQCA gates have advantage of information non-volatility and high resistivity to an ionized particle. In previous studies, MQCA NAND/NOR gates were only demonstrated with two dimensional structures. Therefore, a number of input/output was limited. With 3D-MQCA, we can increase the number of input/output and create a more functional gate in a near future.
To demonstrate the 3D-MQCA gates, we developed a reading and writing method for an individual magnetic layer in nanodots by magnetic force microscopy (MFM). This method will become a powerful tool for basic researches with magnetic multilayer structure.
