Magnetically induced transparency in helically structured periodic crystals
1Far Eastern Federal University, 10 Ajax Bay, Russky Island, Vladivostok 690922, Russia.
Abstract:
We investigated the specific properties of magnetically induced transparency (MIT) and magnetically induced absorption (MIA) in helically structured periodic crystals (HSPCs). We showed that for the wavelength of MIT we have an ideal optical diode: The forward signal passes fully, while the backward signal is completely absorbed and not reflected. A formula for the wavelength λ_{t} of MIT and MIA resonance based on the numerical simulations was analytically obtained. The influence of HSPC parameters on the wavelength λ_{t} and on Δλ_{t}, the transparency line half width, was investigated by numerical simulations. The specific properties of light energy density, the ellipticity e_{in}, and azimuth φ_{in} of the total wave excited in the HSPC layer for MIT and MIA modes were investigated, too.

When atoms or molecules absorb light at the proper frequency, their electrons are excited to higher-energy orbitals. For many main group atoms and molecules, the absorbed photons are in the ultraviolet range of the electromagnetic spectrum, which cannot be detected by the human eye. For coordination compounds, the energy difference between the d orbitals often allows photons in the visible range to be absorbed and emitted, which is seen as colors by the human...

Diffraction
Diffraction is the change in the direction of travel experienced by an electromagnetic wave when it encounters a physical barrier whose dimensions are comparable to those of the wavelength of the light. X-rays are electromagnetic radiation with wavelengths about as long as the distance between neighboring...

To explain the observed behavior of transition metal complexes (such as colors), a model involving electrostatic interactions between the electrons from the ligands and the electrons in the unhybridized d orbitals of the central metal atom has been developed. This electrostatic model is crystal field theory (CFT). It helps to understand, interpret, and predict the colors, magnetic behavior, and some structures of coordination compounds of transition metals.
CFT focuses on...
