We present a rigorous and rather self-contained analysis of the Verdet constant in graphene-like materials. We apply the gauge-invariant magnetic perturbation theory to a nearest-neighbor tight-binding model and obtain a relatively simple and exactly computable formula for the Verdet constant, at ...
nanoparticle and a plurality of organic polymer ligands attached to its surface. The composition can also include a host matrix, such as a polymer, in which the magnetic nanocomposite particles are interspersed therein. The compositions of the invention have the Verdet constant of at least 5000°/...

The relation between the Verdet constant V and the normal Verdet constant VN is explored for diatomic molecules. It is found to depend upon both the mean u and +u excitation energies as well as upon the frequency dependence of the isotropic and anisotropic dipole polarizabilities. An approximate...
The Verdet constant was found to be 38.7rad/(T·m) at a wavelength of 193nm. These results were fitted using the diamagnetic dispersion model and the classical Becquerel formula. The fitted results can be used for the designing of suitable Faraday rotators at various wavelengths. These results...
Since the length of light passing through the object 2 and the strength of the magnetic field generated by the coil 5 can be measured in advance, the Verdet's constant can be calculated by a predetermined formula. the super-conductive coil is employed for generating the magnetic field, and ...
The dispersion formula of the Verdet constant of ZF-7 glass is calculated first, and then, its wavelength accumulation effect upon an optical current sensor is theoretically analyzed and digitally simulated, in this paper. The results show that the wavelength accumulation effect of the Verdet ...
The results show that the rate of change of the Verdet constant at different wavelengths has nothing to do with the Tb 3+ concentration, but only with the effective transition wavelength. The effective transition wavelength of the sample was calculated by the formula, and the source of the ...
1) Verdet constant Verdet常数1. In the PrF_3 crystal,the lowest crystal field state of Pr 3+ ion is a single state,which has no contribution to the susceptibility and the Verdet constant of the crystal in first-order effect. 02556T)×10-5M,在100—300K的温度范围内,以此计算的PrF3晶体...
