Ferromagnetism in Ti-Doped ZnO Nanoclusters above Room Temperature
Journal Article

· IEEE Transactions on Magnetics, 42(10):2697-2699
Ferromagnetism is observed at room temperature, when a small percentage (5%) of non-magnetic titanium is added to zinc atoms to form Ti-doped ZnO nanoclusters in the oxygen atmosphere. The nanocluster films are prepared at room temperature by a technique that is a combination of high pressure sputtering along with aggregation. A Super-conducting Quantum Interference Device (SQUID) measures the magnetic properties of this cluster films at various temperatures. Ti dopant exhibits +4 oxidation state through out the cluster film. Coercivity of the samples decreased exponentially with the increase of temperature.
