Abstract
We propose a simple method for magneto-optic spectroscopy in the terahertz frequency regime without the conventional polarization-resolution technique. It is based on the time-domain reflection spectroscopy and employs circularly polarized terahertz light with magnetic field modulation. We experimentally demonstrate it for an InAs substrate. Our demonstration will help to advance multi-purpose characterization techniques for various semiconductors.
