Abstract
A brief review of theoretical and experimental studies devoted to the design of novel magnetic materials based on non-magnetic semiconductor phases with the ZrCuSiAs structure type (such as LaCuSO, LaCuSeO, LaZnAsO, YZnAsO, or SrAgSeF) by doping their sublattices with magnetic and non-magnetic substitutional impurities is presented. Using the results of
ab initio calculations of the band structure, we discuss the possibility of obtaining new magnetic semiconductors, magnetic metals and half-metals, and also gapless magnetic semiconductors and bipolar magnetic semiconductors based on the 1111 phases. The available experimental data on the synthesis and properties of materials based on semiconducting 1111 phases doped with atoms of alkali-earth and magnetic 3
d metals are discussed.
