We highlight a method based on itinerant magnetism for finding ferromagnetic semiconductors that can be gate tuned to study quantum critical points. We demonstrate that p-type FeAs2 is an example. The complex nonparabolic band structure of this material leads to a ferromagnetic instability when doped, while at the same time allowing for a modest transport effective mass. This leads to an analogy between magnetic semiconductors and thermoelectric materials.
