    New Paper Published

    June 14, 2022

    Golam's recent paper entitled "Positional Stability of Skyrmions in a Racetrack Memory with Notched Geometry (link)" published in Physical Review Applied. Hamed Vakili shared equal authorship in this paper. In this paper, we solve micromagnetic equations to simulate skyrmion trajectories and extract quasi-analytical equations for their energy barrier and their dependence on the material and geometrical properties of the racetrack. Our numerical study shows that it is indeed possible to create constrictions designed along a racetrack that can hold the skyrmions in place long enough for meaningful information storage, yet easily cleared with a modest current pulse.

    New Paper Published

    August 23, 2021

    We are glad to share that our invited perspective article “Skyrmionics - Computing and Memory Technologies based on Topological Excitations in Magnets” has been published in the Journal of Applied Physics. In this article, we have discussed the state-of-the-art skyrmion-based technology from fundamentals to applications. This article is a collaborative effort between six different groups in three Universities (UVA, NYU, and MIT) working under the DARPA "Topological Excitations in Electronics (TEE) Program" for the last couple of years. 

    Anyone working and/or interested in this research area might find this article very useful.
