Ferromagnetic Behavior and Magneto-Optical Properties of Semiconducting Co-Doped ZnO.

ZnO is a well-known semiconducting material showing a wide bandgap and an -type intrinsic behavior of high interest in applications such as transparent electronics, piezoelectricity, optoelectronics, and photovoltaics. This semiconductor becomes even more attractive when doped with a few atomic percent of a transition metal. Indeed, e.
