Systematic study of magnetic linear dichroism and birefringence in (Ga,Mn)As
N. Tesarova, T. Ostatnicky, V. Novak +12
Magnetic linear dichroism and birefringence in (Ga,Mn)As epitaxial layers is investigated by measuring the polarization plane rotation of reflected linearly polarized light when ma…
High Precision Magnetic Linear Dichroism Measurements in (Ga,Mn)As
N. Tesarova, J. Subrt, P. Maly +4
Investigation of magnetic materials using the first-order magneto-optical Kerr effects (MOKE) is well established and is frequently used in the literature. On the other hand, the u…
Terahertz Magneto Optical Polarization Modulation Spectroscopy
D. K. George, A. V. Stier, C. T. Ellis +3
We report the development of new terahertz techniques for rapidly measuring the complex Faraday angle in systems with broken time-reversal symmetry using the cyclotron resonance of…
Terahertz dynamics of a topologically protected state: quantum Hall effect plateaus near cyclotron resonance in a GaAs/AlGaAs heterojunction
A. V. Stier, C. T. Ellis, H. Zhang +5
We measure the Hall conductivity of a two-dimensional electron gas formed at a GaAs/AlGaAs heterojunction in the terahertz regime close to the cyclotron resonance frequency by empl…
