“…The magnetooptical Kerr effect (MOKE) has potential application in ultrathin magnetic devices, e.g. films [8], multilayers [9], and magnetic superlattices [10], and, the surface magneto-optic Kerr effect (SMOKE) has remain a powerful tool for in situ characterization [11] . All the setups have shown bistability as their predominant characteristics which causes due to nonlinear susceptibility.…”

“…The magneto-optical Kerr effect (MOKE) exhibits importance in the application in ultrathin magnetic devices, e.g. magnetic superlattices [5], films [6] and multilayers [7]. The Kerr nonlinearity has shown some interesting quantum phenomena such as photon bunching and antibunching [8], photon switching in quantum interference [9], dynamical optical bistability via bifurcation process [10] and the generation of non-classical states [11].…”

We simulate coherent driven free dissipative Kerr nonlinear system numerically using Euler's method by solving Heisenberg equation of motion and time evolving block decimation (TEBD) algorithm, and demonstrate how the numerical results are analogous to classical bistability. The comparison with analytics show that the TEBD numerics follow the quantum mechanical exact solution obtained by mapping the equation of motion of the density matrix of the system to a Fokker-Plank equation . Comparing between two different numerical techniques, we see that the semi-classical Euler's method gives the dynamics of the system field of one among two coherent branches, whereas TEBD numerics generate the superposition of both of them. Therefore, the time dynamics determined by TEBD numerical method undergoes through a non-classical state which is also shown by determining second order correlation function.

“…Next, resonant TMOKE can be used to read out the in-plane magnetization of the system which is appealing for possible applications in quantum information and sensing technologies [36,37]. Typically, the spin dynamics in semiconductors are assessed by the polarization rotation due to the Faraday effect or Polar Kerr effect (PMOKE) [38]. The experimental studies were performed on the following two set-ups.…”

Transverse magneto-optical Kerr effect at narrow optical resonances

Magneto-optical spectroscopy based on the transverse magneto-optical Kerr effect (TMOKE) is a sensitive method for investigation of magnetically-ordered media. However, in magnetic materials the optical transitions are usually characterized by spectrally broad resonances with widths considerably exceeding the Zeeman splitting in the magnetic field. Here we investigate experimentally and theoretically the TMOKE in the vicinity of relatively narrow optical resonances provided by confined quantum systems.

Reflectance difference spectroscopy (RDS) and photoluminescence spectroscopy on digital magnetic heterostructures are presented. From the angular dependence of the RDS spectra, signals due to interband Faraday rotations and signals originating from crystal anisotropy, can be distinguished. The Faraday rotation follows the Curie‐Weiss behaviour with an antiferromagnetic temperature of —6K corresponding to the nominal ion spin concentration in the magnetic barriers.
