Local optical control of ferromagnetism and chemical potential in a topological insulator
Andrew L. Yeats, Peter J. Mintun, Yu Pan +4
Many proposed experiments involving topological insulators (TIs) require spatial control over time-reversal symmetry and chemical potential. We demonstrate reconfigurable micron-sc…
Persistent Optical Gating of a Topological Insulator
Andrew L. Yeats, Yu Pan, Anthony Richardella +3
Topological insulators (TIs) have attracted much attention due to their spin-polarized surface and edge states, whose origin in symmetry gives them intriguing quantum-mechanical pr…
Spin Transfer Torque Generated by the Topological Insulator Bi_2Se_3
A. R. Mellnik, J. S. Lee, A. Richardella +8
Magnetic devices are a leading contender for implementing memory and logic technologies that are nonvolatile, that can scale to high density and high speed, and that do not suffer…
