Description

In this paper, the structural and magnetic properties of Ni metal implanted TiO2 single crystals are discussed. Ni nanocrystals (NCs) have been formed in TiO2 after ion implantation. Their crystallite sizes increased 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 make the major contribution to the measured ferromagnetism. - Highlights: → Correlation between structure and magnetism in Ni-implanted TiO2. → Origin of ferromagnetism in Ni-implanted TiO2. → Post-annealing on magnetic and structural properties of Ni-implanted TiO2.
