We investigate the effect of magnetic neighbor interaction on the state behavior of nano-magnetic disks for data storage and computation applications. We have observed and verified that a nano-magnetic disk, with certain dimension, can exist either in the single domain state or in the vortex state depending on the edge-to-edge spacing between the nano-magnetic disks. The experiments were conducted...
The coupling among nano-magnets, placed at specific locations, but not necessarily in a regular grid, can be used to perform logic operations. We have developed an image-processing tool that will help one to automatically analyze and characterize atomic force microscopy (AFM) images and magnetic force microscopy (MFM) images of fabrication attempts to identify errors and magnetization. This is currently...
This work is an effort to introduce short knowledge modules targeting new application or emerging devices in conventional “core” courses. In this knowledge module, we report introduction of two emerging devices, Memristor and Magnetic Cellular Automata. Both the devices also have potential to work as memory and logic simultaneously. Based on the worksheet performance, we observed that students were...
Single domain magnets serve as an excellent mechanism to store and preserve Boolean information. This work is an effort to establish that information can not only be stored and altered as in memory but also can be propagated in a causal fashion from the driver to the driven cell in presence of an external clocking field.
