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 CrO(2)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 ide...
