Summary
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 Prof. Zhu at CSNS, Prof. Panagopoulos at NTU, and Profs. Månsson and Delin at KTH. By integrating neutron scattering (at CSNS) with advanced thin film synthesis and characterizations (at NTU), and complementary X-ray and muon techniques, the project will build a robust experimental framework directly aligned with current and future PNR and GISANS capabilities at ESS, particularly ESTIA instrument.
