Giant natural optical rotation from chiral electromagnons in a collinear antiferromagnet
D. Maluski, M. Langenbach, D. Szaller +8
In NiTeO with a chiral crystal structure, we report on a giant natural optical rotation of the lowest-energy magnon. This polarization rotation, as large as 140 deg/mm, cor…
Magnetoelectric coupling in the mixed erythrosiderite [(NH)K][FeCl(HO)]
Daniel Brüning, Tobias Fröhlich, Malte Langenbach +7
We present a study of the dielectric, structural, and magnetic properties of the multiferroic or linear magnetoelectric substitution series [(NH)K][FeCl(H$_…
Self-normalizing phase measurement in multimode terahertz spectroscopy based on photomixing of three lasers
K. Thirunavukkuarasu, M. Langenbach, A. Roggenbuck +4
Photomixing of two near-infrared lasers is well established for continuous-wave terahertz spectroscopy. Photomixing of three lasers allows us to measure at three terahertz frequenc…
Group delay in THz spectroscopy with ultra-wideband log-spiral antennae
M. Langenbach, A. Roggenbuck, I. Cámara Mayorga +4
We report on the group delay observed in continuous-wave terahertz spectroscopy based on photomixing with phase-sensitive homodyne detection. We discuss the different contributions…
Enhancing the stability of a continuous-wave terahertz system by photocurrent normalization
A. Roggenbuck, M. Langenbach, K. Thirunavukkuarasu +6
In a continuous-wave terahertz system based on photomixing, the measured amplitude of the terahertz signal shows an uncertainty due to drifts of the responsivities of the photomixe…
