Magnetization relaxation and search for the magnetic gap in bulk-insulating V-doped (Bi, Sb)Te
E. Golias, E. Weschke, T. Flanagan +9
V-doped (Bi,Sb)Te has a ten times higher magnetic coercivity than its Cr-doped counterpart and therefore is believed to be a superior system for the quantum anomalous Hall…
Helicity dependent photocurrent in electrically gated (Bi,Sb)_2Te_3 thin films
Yu Pan, Qing-Ze Wang, Andrew L. Yeats +7
Circularly polarized photons are known to generate a directional helicity-dependent photocurrent in three-dimensional topological insulators at room temperature. Surprisingly, the…
Ferromagnetism and Spin-dependent Transport in n-type Mn-Bi2Te3 Thin Films
Joon Sue Lee, Anthony Richardella, David W. Rench +5
We describe a detailed study of the structural, magnetic, and magneto-transport properties of single-crystal, n-type, Mn-doped Bi2Te3 thin films grown by molecular beam epitaxy. Wi…
Growth and Characterization of Hybrid Insulating Ferromagnet-Topological Insulator Heterostructure Devices
A. Kandala, A. Richardella, D. W. Rench +3
We report the integration of the insulating ferromagnet GdN with epitaxial films of the topological insulator Bi2Se3 and present detailed structural, magnetic and transport charact…
Interplay between ferromagnetism, surface states, and quantum corrections in a magnetically doped topological insulator
Duming Zhang, Anthony Richardella, David W. Rench +12
The breaking of time-reversal symmetry by ferromagnetism is predicted to yield profound changes to the electronic surface states of a topological insulator. Here, we report on a co…
