Abstract

A series of copper-doped zinc oxide films were grown by pulsed-laser ablation. Films grown under conditions that produced n -type ZnO were nonmagnetic while those grown under conditions that produced p -type were ferromagnetic with a Curie temperature above 350 K. The magnetic moment per copper atom decreased as the copper concentration increased. An explanation for this result is proposed based on the distance between nearest-neighbor copper atoms.
