A series of Zn{sub 0.85−x}Mg{sub x}Co{sub 0.15}O (0 ≤ x ≤ 0.3) thin films were fabricated by plasma-assisted molecular-beam epitaxy to investigate the correlation between the electrical transport properties and the ferromagnetism. It is observed that the saturation magnetization remains almost uncha...
