Abstract
We report the first observations of ferromagnetism above room temperature for small atomic percentages of Mn doped in ZnO. In a homogeneous bulk pellet sample sintered at low temperatures ({approx}500 deg. C) Mn is found to carry an average moment of 0.16 {mu}{sub B} per Mn ion. We have obtained room temperature ferromagnetic ordering in samples containing around 2% Mn in the form of powder, bulk pellets and 2-3 {mu}m thick transparent laser-ablated films. The new capability to fabricate ferromagnetic Mn-doped ZnO semiconductors promises new devices related to spintronic devices as well as magneto-optic components.
