Sheikh defended his Dissertation

Congratulations, Sheikh. He defended his dissertation today. We celebrated his success by having a group dinner. 

New Paper Published

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.

New Paper Published

Golam's co-authored paper (led by Quessab et al. at NYU) entitled "Interplay between Spin-Orbit Torques and Dzyaloshinskii-Moriya Interactions in Ferrimagnetic Amorphous Alloys (link)" published in Advanced Science. In this paper, we investigate a simultaneous control of spin-orbit torques (SOTs) and Dzyaloshinskii-Moriya interactions (DMI) in amorphous ferrimagnetic alloys to pave the way for energy-efficient current-induced domain wall or skyrmion motion.

Golam's recent paper entitled "Tuning Dzyaloshinskii-Moriya interaction in ferrimagnetic GdCo: A first-principles approach (link)" published in PRB. In this article, we explore the impact of cap layer composition and different cap layer heavy metals on the  Dzyaloshinskii-Moriya Interaction (DMI). We also show the effect of structural arrangements (to mimic the experimentally realistic structures) on the DMI.
