ZnO single crystals were implanted with Mn, Co and Ni with fluences between 1 × 10<Superscript>16</Superscript> cm<Superscript>-2</Superscript> and 1 × 10<Superscript>17</Superscript> cm<Superscript>-2</Superscript> and energy of 200 keV. Results indicate that aggregation of transition metal ions in the as implanted state occurs only in the case of Ni. After an annealing stage to recover the ZnO...</superscript></superscript></superscript></superscript>

The magnetic and electrical properties of Co-implanted single crystalline TiO<Subscript>2</Subscript> rutile are presented. For fluences of the order of 10<Superscript>17</Superscript> cm<Superscript>-2</Superscript> and implantation energy of 150 keV the maximum atomic concentration of cobalt is 13 at% at a depth of 65 nm from the surface. The as implanted single...</superscript></superscript></subscript>

The magnetic properties of Co and Ni nanosized aggregates formed after implantation of nickel and cobalt ions in magnesium oxide single crystals were investigated. The influence of the implantation energy and annealing treatments was characterized. The particle size distribution was determined...
