摘要: Knowledge of the magnetic ordering temperature is one fundamental physical properties characterizing material behavior. Magnetism not only related to magnitude moments within specific ordering, but it also influences other properties. In present work, we determine temperatures for high-entropy alloys (HEAs), with examples Al- and Mo-based Cantor alloy derivatives. Nowadays, HEAs represent a promising class materials in sense mechanical engineering. Regarding paramagnetic state well-known well-explored alloy, deal its Mo Al derivatives, which offer higher possible temperatures. We discuss differences between $p$-type $d$-type substitution as well their influence on based ab initio calculated exchange interactions terms mean-field approximation, random-phase Monte Carlo simulations. Based thorough description pair interactions, particular composition's achieved critical described.
