Abstract
We investigated the structural and magnetic properties of Zn0.95Mn0.05O films prepared on sapphire substrates by pulsed-laser deposition. Only low temperature ferromagnetism (Curie temperature lower than 50Â K) was observed in Mn-doped samples, while pure ZnO film shows a typical paramagnetic behavior. Structural analyses indicate that the substitutional Mn2+ ions play a significant role for the low temperature ferromagnetism. Lattice defects such as VO and VZn were not proven to be effective factors for the origin of ferromagnetism in the films. The low temperature ferromagnetism might be interpreted as p-d hybridization from indirect coupling of Mn ions (Mn-O-Mn).
