Magnetic Nanowire Memory Utilizing Motion of Magnetic Domains for Developing a High-speed Recording Device

摘要

We have proposed magnetic memories utilizing parallel nanowires with no mechanical moving parts, in order to achieve ultra-high data transfer rates required for three-dimensional video. In an experiment, we used a structure consisting of a magnetic nanowire and a magnetic head used in a commercial hard disk drive, in which a pair of a write head and a read head was placed in line. A magnetic nanowire memory element was constructed by fixing the magnetic head onto a fabricated nanowire. We conducted a performance test of recording, bit-shifting, and detecting data in the memory element and succeeded in demonstrating the fundamental principle of the magnetic nanowire memory.
