Giant plateau in the THz Faraday angle in gated Bi2Se3
Gregory S. Jenkins, Andrei B. Sushkov, Don C. Schmadel +5
We report gated terahertz Faraday angle measurements on epitaxial Bi2Se3 thin films capped with In2Se3. A plateau is observed in the real part of the Faraday angle at an onset gate…
Terahertz Kerr and Reflectivity Measurements on the Topological Insulator Bi2Se3
G. S. Jenkins, A. B. Sushkov, D. C. Schmadel +4
We report the first terahertz Kerr measurements on bulk crystals of the topological insulator Bi2Se3. At T=10K and fields up to 8T, the real and imaginary Kerr angle and reflectanc…
Infrared anomalous Hall effect in SrRuO: Evidence for crossover to intrinsic behavior
M. -H. Kim, G. Acbas, M. -H. Yang +7
The origin of the Hall effect in many itinerant ferromagnets is still not resolved, with an anomalous contribution from the sample magnetization that can exhibit extrinsic or intri…
Electronic structure of ferromagnetic semiconductor Ga1-xMnxAs probed by sub-gap magneto-optical spectroscopy
G. Acbas, M. -H. Kim, M. Cukr +6
We employ Faraday and Kerr effect spectroscopy in the infrared range to investigate the electronic structure of Ga1-xMnxAs near the Fermi energy. The band structure of this archety…
Determination of the infrared complex magneto-conductivity tensor in itinerant ferromagnets from Faraday and Kerr measurements
M. -H. Kim, G. Acbas, M. -H. Yang +8
We present measurement and analysis techniques that allow the complete complex magneto-conductivity tensor to be determined from mid-infrared (11-1.6 micron; 100-800 meV) measureme…
