Spintronic devices explore the spin property of electrons along with charge to store, process and transmit the information. The spintronic technology can potentially outperform conventional microelectronic technology due to its attractive features such as non-volatility, fast switching and radiation hardness. It can take one of the two states relative to the magnetic field, generally known as “up” and “down”. These two directions can be assigned to two binary data bits “1” and “0”. Spin based devices, principally known as “spintronic” devices have remarkable advantages over the existing technology. The spin switching is much faster than the charge transfer. The lower power consumption and high endurance make them attractive for future technological applications. Above all, the spin-based devices are fascinating as they exhibit non-volatile data retention even after the power is removed. Magnetic spin textures are of great interest to implement spin based logic where the operations are not driven by the magnetostatic interactions between the nanomagnets in MQCA-based logic. In the recent past, magnetic domain walls have been employed to process both boolean and non-boolean logic operations [ref]. Some more details. Another emerging spin texture which is being considered as the most promising alternat=ive to electronic technologies is a skymion. Recently logic and memory devices based on magnetic skyrmions attracting great interest. Skymrions are nano-scale swirling spin textures with topological protection that exhibit particle-like behaviour. Skyrmions can be potentially used as information carriers because of their nanoscale size. In this project we aim to demonstrate new spin logic architecture based on these exotic spin textures like magnetic domain walls and magnetic skyrmions. The example embodiments described herein seek to address or at least alleviate the above problems.
