Abstract The structural and magnetic properties of Ni-implanted rutile single crystals are discussed. Ni nanocrystals (NCs) are formed in TiO2 after ion implantation. Their crystalline sizes increase with increasing post−annealing temperature. Metallic Ni nanocrystals inside the TiO2 matrix are stable up to an annealing temperature of 1073 K. The Ni NCs formed inside TiO2 are the major contribution to the measured ferromagnetism.
