Realization of room-temperature ferromagnetism and of improved carrier mobility in Mn-doped ZnO film by oxygen deficiency, introduced by hydrogen and heat treatments
The room-temperature ferromagnetic (RTFM) ordering with a very low carrier mobility occurs in polycrystalline Mn-doped ZnO film with delta similar to 0.04. We successfully fabricated RTFM Zn0.96Mn0.04O:H film with a substantially improved carrier mobility (similar to 400% larger than that of the as-grown sample) through the hydrogen-implantation and a subsequent heat treatment.
