Novel Topological Spin Structure via Interface Engineering Design

As cloud computing and artificial intelligence (AI) are expanding, the digital age of modern civilization is producing an overwhelming amount of data that significantly increased the need for storage and processing power.

In that regard, spintronics is a promising technology because it manipulates the intrinsic spin of electrons, along with their charge and magnetic moment, thus minimizing energy loss.

As novel information carriers, magnetic skyrmions have attracted interest due to their unique topology, nano size, defect tolerance, and low power requirements.

However, to achieve sustainable, energy efficient, and reliable devices based on skyrmion, a fundamental understanding of their emergence, stability, and quantum entanglements is required.This project aims at designing new topological spin structures beyond traditional magnetic skyrmions, arising from interface engineering of magnetron-sputter-epitaxy grown superlattices to alter the interfacial magnetic properties and tuning the static and dynamic behaviors of skyrmions.I will lead this project in collaboration with Profs.

Panagopoulos and Shen at NTU and Prof. Sassa at KTH.

I will spend two years at NTU, exploring new skyrmion systems, learn and perform magnetic/electronic characterizations with state-of-the-art facilities at NTU.

For the remaining year at KTH, I learn about the fundamental physics behind topological systems and implementing new strategies for interface engineering of such topological spin structures.
