Room-temperature ferromagnetism in diluted magnetic zinc oxide semiconducting nanomaterials
The diluted magnetic zinc oxide semiconducting nanomaterials were synthesized via a solvothermal method. The obtained ZnO nanocrystals with different percentage of transition metal dopant have room-temperature ferromagnetism. The X-ray diffraction spectra indicate that all the samples show good diluted magnetic semiconductor structures. The results show that the magnetic metals ions substitute zinc ions in the hexagonal ZnO lattice, and part of them are ferromagnetically coupled up to room temperature even in isolated noninteracting nanocrystals.
