"Magnetic Skyrmions and Magneto-Ionics"

The coming end of Moore’s law underscores the need for transformative new approaches beyond the complementary metal-oxide semiconductor (CMOS) technology.

Nanomagnetics and Spintronics offer an exciting new paradigm to address this grand challenge. For example, in recently discovered magnetic skyrmions, mostly at low temperatures, the unique spin texture and the topologically protected quantum state offer great potentials for low dissipation magnetic information storage. We have recently demonstrated the realization of room temperature artificial Bloch skyrmion lattices in their ground state.

In a second area, we have demonstrated effective magneto-ionic manipulation of metal/oxide interfaces due to a redox-driven oxygen migration, manifested through the interface-sensitive exchange bias effect and controllable under an electric field. Similar effects are found in getter/perovskite systems of Gd/LaSrMnO₃ and Gd/LaSrCoO₃.

Time permitting, I will also discuss results in high anisotropy L1₀ FePt for heat assisted magnetic recording. These results show promise towards future spin-based nanoelectronics and information storage.
