Abstract:

The switching behavior of the nanomagnet logic device with the single missing corner shape defect is studied. We use micromagnetic simulation software to investigate preferred magnetization of the said peculiar shape nanomagnet logic device under various missing corner ranges, nanomagnet thicknesses and material parameters. The results indicate that the preferred magnetization of the missing corner-type nanomagnet logic device fabricated with different materials appears in the neighboring critical missing corner amplitude, and that the nanomagnet fabricated with Permalloy is susceptible to the missing corner shape defect, higher saturation magnetization and thicker magnetic film block preferred magnetization of peculiar shape devices. These findings provide key theoretical parameters for how to control and apply the preferred magnetization of the peculiar shape nanomagnet logic device.

Key words: nanomagnet logic device, switching behavior, preferred magnetization, peculiar shape
