Abstract:
The high-spin-polarized electronic state has been a central concept in applications such as storage materials and magnetic injection sources. In this work, we predicted the existence of a novel 2D CrO2 lattice, wherein electrons around the Fermi level were indicated to be completely spin-polarized with an ultra-wide energy range. Monte Carlo simulations showed that such an ordered spin state could be maintained to a temperature of 280 K, and further enhanced through strain or hole doping. The predicted structure here inspired us to archive ideal 2D materials as magnetic storage devices or spin injection sources.

Crystal Field Theory - Octahedral Complexes
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...
