Abstract

We investigate the optical properties of a hexagonal lattice with spin-spin interaction. Transition metal atoms with 3d-orbitals, for example Cr, Fe, Co, Ni, can be embedded in the lattice, exhibiting a strong magnetic moment. Spin polarization controls the magnetic phases, which can be ferromagnetic (FM), ferrimagnetic (FR), or antiferromagnetic (AFM). The behavior of electrons can resemble both massless and massive particles when varying the angle between spin-spin interactions. This leads to the investigation of the electronic properties of alternative materials, such as MXenes, for optoelectronic devices with stable transmission across a wide range of light frequencies from near-infrared to the ultraviolet regime. Furthermore, anisotropic optical conductivity and transmittance could be used to identify the spin orientation and atomic arrangement in magnetic materials.
