Strong transient magnetic fields induced by THz-driven plasmons in graphene disks
Nature Communications, 2023 Strong circularly polarized excitation opens up the possibility to generate and control effective magnetic fields in solid state systems, e.g., via the optical inverse Faraday effect or the phonon inverse Faraday effect.

Measurement of the Verdet Constant of Polarization-Maintaining Air-Core Photonic Bandgap Fiber
Sensors, 2017 We propose a method based on the white-light interference technique for measuring the Verdet constant of a polarization-maintaining air-core photonic bandgap fiber (PM-PBF).

Growth Parameters of Fully Crystallized YIG, Bi:YIG, and Ce:YIG Films With High Faraday Rotations
IEEE Photonics Journal, 2014 We report on the growth of thin films of yttrium iron garnet (YIG) on dielectric substrates. Such films have historically been challenging to grow due to either cracking or incomplete crystallization of the films.

Small Science, 2022 The Faraday rotation originates from the mechanism by which the time‐reversal symmetry in the material is broken by the external magnetic field. It is the basis for the development of some magneto‐optical devices, such as optical isolators. In integrated

Faraday effect in semiconductors [PDF]
Proceedings of the Royal Society of London. Series A. Mathematical and Physical Sciences, 1962 Abstract This paper first reviews the general macroscopic and quantum mechanical formulae necessary for the calculation of Faraday rotations and Voigt shifts in semiconductors. The general formulae are then applied to calculate Faraday rotations, θ, in semiconductors as caused by: (i) allowed direct band-to-band transitions, (ii ...

Transient spectral dependence of photoinduced magneto-optical Faraday effect in CdTe quantum dots
AIP Advances, 2012 The time-resolved photo-induced magneto-optical response of water soluble cadmium telluride (CdTe) colloidal quantum dots (QDs) is studied in the spectral range across the first exciton (1S3/21Se) transition at room temperature without external magnetic ...

Untangling Cosmic Magnetic Fields: Faraday Tomography at Metre Wavelengths with LOFAR
Galaxies, 2018 The technique of Faraday tomography is a key tool for the study of magnetised plasmas in the new era of broadband radio-polarisation observations. In particular, observations at metre wavelengths provide significantly better Faraday depth accuracies ...
