Magneto-optical Kerr effect in surface engineered 2D hexagonal boron nitride

“…In this relation, the sign convention has been considered so that for clockwise rotation of the incoming beam, is positive. The relation between and with the dielectric tensor, is as follows 24 after some simplification and considering our polar specific case the final relation for the Kerr effect will be 27 where and stand for the diagonal and off-diagonal elements of dielectric tensor, respectively. In order to evaluate the Kerr effect, two important related spectral quantities, optical conductivity tensor, and dielectric tensor come into consideration.…”

Adsorption of NOx (x = 1, 2) Molecules on the CoFeMnSi(001) Surface: First-Principles Insights

“…Equi-atomic quaternary Heusler alloys with a general formula ABCD and stoichiometry of 1:1:1:1 have received much attention recently due to their extraordinary properties . The spin-gapless semiconductor Heuslers have zero band gap for the majority electrons while they have non-zero band gap for the minority electrons; thus, they can be utilized for multiple applications including spintronic devices . Devices based on these alloys have low power dissipation than the pseudo ternary alloys because of the lower length of spin diffusion …”

Magneto-Optical Kerr effect in surface engineered 2D hexagonal boron nitride

“…3 DFT calculations are extensively used on MOKE for 2D materials and Heusler alloys, revealing the effect of strongly bounded excitons of charge-transfer on magneto-optical properties, interband transitions, spin-orbit coupling, and half-metallic geomagnetism in such magnetic materials. 20,[22][23][24] In this work, we take into consideration different levels of surface functionalization and low-level doping as the advanced methods of surface engineering. We have extensively investigated the optical properties of these materials.…”
