Time dependent Faraday rotation
@article{Gevorkian2017TimeDF, title={Time dependent Faraday rotation}, author={Zhyrair S. Gevorkian and Vladimir Gasparian and Josh Lofy}, journal={Laser Physics}, year={2017}, volume={28} }
Faraday rotation in a magnetoactive medium with time dependent dielectric permittivity tensor is analyzed through both its diagonal and non-diagonal elements. Continuous and pulse incident laser field cases are considered. In a continuous case linear increasing of Faraday rotation angle with time is obtained. In the continuous laser field case Faraday angle of rotation in both time dependent diagonal and non-diagonal element cases shows an increase with periodic oscillations as either positive…

This work proposes an experimental situation where a time lag should appear, allowing measurement of the spin-lattice relaxation time of the ion responsible for the Faraday rotation, and shows that this effect is an artifact introduced by using a passive resistance-capacitance circuit to integrate the induced electromotive force from a pickup coil to obtain the magnetic field.

The photoinduced magnetization is found to be increased in a transient manner, accompanied with subsequent demagnetization, and the realization of the transient collective ordering is attributable to the enhancement of the f-d exchange interaction.
