Magnetic semiconductors combine the complementary functions of magnetic and semiconducting materials, providing tremendous potential for the development of new devices for today’s information technology. If employed in devices, these materials could lead to a new pathway to control information: by charging carriers not only in traditional electronics, but also in spin dimensions. The Zener model was modified by Dietl et al. to explain the origin of ferromagnetism in Mn-doped GaAs and predicted the room-temperature ferromagnetism in other semiconductors and oxides. This remarkable work opened up the era of searching for room-temperature ferromagnetism in semiconductors. It still remains a lot of work to identify plausible targets for new magnetic materials. Previous studies mainly focused on hybrid structures consisting of ferromagnetic and semiconducting multilayers and Mn-doped binary semiconductors. However, only a small handful of intrinsic magnetic semiconductors have thus far been reported. Thus, design of specifically targeted by synthetic scientists is highly demanded. In this talk I will describe some empirical design rules and examples that have yielded new magnetic semiconductors/semimetals.<br/>
