Search for ferromagnetism in transition-metal-doped piezoelectric ZnO
We present results of a computational study of ZnO in the presence of Co and Mn substitutional impurities. The goal of our work is to identify potential ferromagnetic ground states within the (Zn,Co)O or (Zn,Mn)O material systems that are also good candidates for piezoelectricity. We find that robust ferromagnetism is …
