The room‐temperature ferromagnetic (RTFM) ordering with a very low carrier mobility occurs in polycrystalline Mn‐doped ZnO film with δ ∼ 0.04. We successfully fabricated RTFM Zn 0.96 Mn 0.04 O:H film with a substantially improved carrier mobility (∼ 400% larger than that of the as‐grown sample) through the hydrogen‐implantation and a subsequent heat treatment.
