Infrared Hall Effect in the electron-doped high Tc cuprate Pr(2-x)Ce(x)CuO(4)
A. Zimmers, L. Shi, D. C. Schmadel +10
The electron-doped cuprate Pr(2-x)Ce(x)CuO(4) is investigated using infrared magneto-optical measurements. The optical Hall conductivity sigma_{xy} shows a strong doping, frequency…
Laser Driven Nuclear physics at ELINP
F. Negoita, M. Roth, P. G. Thirolf +53
High power lasers have proven being capable to produce high energy gamma rays, charged particles and neutrons to induce all kinds of nuclear reactions. At ELI, the studies with hig…
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…
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…
Measurement of the infrared complex Faraday angle in semiconductors and insulators
M. -H. Kim, V. Kurz, G. Acbas +2
We measure the infrared (wavelength 11 - 0.8 microns; energy E = 0.1 - 1.5 eV) Faraday rotation and ellipticity in GaAs, BaF2, LaSrGaO4, LaSrAlO4, and ZnSe. Since these materials a…
